Passing values to a LINKSCREEN in PH Web

It still doesn't work. I find the cheque record using the CORP_CUST_ID
field and it displays on the web page. I then enter an invoice number I
*know* exists (99998) for that corp_cust_id (75) and click on the button.
The screen flickers like it's refreshing itself but nothing else happens.
I then look at the source for the page in the browser and I see that the
invoice number entered is correct:
<td width="18"><input type="text" size="14" name="t_invoice_nbr"
value="99998"></td>
Using the JavaScript method, I don't see where the data values are being
passed to the called screen in the web page. Is this hidden? How can I
test the JavaScript to make sure the data values are being passed?
Here is the QKS and HTML logic used in the calling screen:
HTML
<script language="JavaScript">
<!--
function CheckApplied() {
if ((self.document.postchk.amount.value) <
(self.document.postchk.amount_applied.value)) {
alert("*E* Check amount cannot be less than amount applied!");
}
}
function UserAction(action)
{
self.document.postchk.PH_ACTION.value = action;
self.document.postchk.submit();
}
//-->
</script>
...
<form action="/cgi-bin/phcgi.exe" method="POST" name="postchk">
...
<table width="60%" cellpadding="0" cellspacing="0" frame="void">
<tr>
<td align="right"><B><I>Invoice Number </i></b></td>
<td width="18"><input type="text" size="14" name="t_invoice_nbr"
value="99998"></td>
<td><input type="button" onclick="UserAction('CINV')" value="Select Specific
Invoice">/td>
</tr>
</table>

Did you use NODATA for the designer procedure?

Thanks Simon
I tried a designer procedure like you said but when I click on it, the
screen flickers bit and nothing else happens! :(
Can I use debug with PH Web screens?

Hi Bob
I confess I've not fully read through all you supplied in detail, but it
sounds as if you're getting your Client Side (in this case JavaScript in the
browser) and Server Side (in this case PowerHouse Web) slightly mixed up.
The values passed in the <A HREF..> link are generated on the SERVER, and by
having the user enter a value and immediately clicking the link, you never
go back to the server and get the link regenerated to reflect the changed
value.
Instead of having your users click on a link after entering the value,
consider giving them a button instead. You could then change your
LINKSCREEN to a DEFER LINKSCREEN within a designer procedure linked to that
button. You may also need to code ACCEPT statements for all the values you
pass.
Have fun.
Simon.

G'day all, again
Ok, so now my JavaScript is 'maybe' resolved. What I'm trying to do is call
one screen from another like so.
Screen A.
User enters a customer id, finds related records in results list and data is
loaded for selected record (happens to be a cheque).
User enters an invoice number (temp item) on screen and clicks link to
subscreen (screen B) to see invoice detail (actually could be several
records as invoice number is not unique). There user selects invoice record
and is taken to a posting screen to apply part or all of the cheque value to
the selected invoice (screen C).
In screen A the logic is:
QKS
...
TEMP t_invoice_nbr VARCHAR*15 RESET AT STARTUP
TEMP t_invoice CHAR*01 INIT "Y"
...
FIELD t_invoice_nbr LABEL "Invoice #:" &
LOOKUP ON post_invoice &
MESSAGE "*E* Invoice not found!"
FIELD t_invoice NOLABEL
...
LINKSCREEN pc_select_invoice LABEL "Select Invoices" &
ACTION "SEARCH" &
PASSING corp_cust_id AS "POST_INVOICE:corp_cust_id", &
t_invoice_nbr AS "POST_INVOICE:invoice_nbr", &
check_nbr AS "t_check_nbr", &
check_date AS "t_check_date", &
amount AS "t_check_amount", &
amount_applied AS "t_amount_applied", &
amount_open AS "t_amount_open", &
t_invoice_status AS "t_invoice_status", &
check_key AS "t_check_key", &
t_invoice, &
t_sort_inv_nbr
HTML
<input type="hidden" size="1" name="T_INVOICE"

</td>
</tr>
</table>
In screen B the logic is:
QKS

END
HTML
<tr>
<td>Corp Cust Id</td>
<td><input type="text" size="11" name="POST_INVOICE:Corp_cust_id"
value="<!--PH:VALUE:POST_INVOICE:Corp_cust_id-->"></td>
</tr>
<tr>
<td>Invoice Nbr</td>
<td><input type="text" size="15" name="POST_INVOICE:invoice_nbr"
value="<!--PH:VALUE:POST_INVOICE:invoice_nbr-->"></td>
</tr>
<tr>
...
<input type="hidden" size="1" name="T_INVOICE"
value="<!--PH:VALUE:T_INVOICE-->">
Now for the problem.
When the user enters an invoice number in the t_invoice_nbr field and clicks
on the link, the value for POST_INVOICE:invoice_nbr is not being passed.
How do I make the screen pass this value?
Here is what is being passed at run-time:
<A
HREF="/cgi-bin/phcgi.exe?PH_QKC=pc_select_invoice&PH_APP=CORPCUST_APP&am
p;PH_HTML=pc_select_invoice.htm&PH_ACTION=Search&POST_INVOICE:corp_c
ust_id=0&POST_INVOICE:invoice_nbr=&t_check_nbr=98765&t_check_dat
e=06/10/01&t_check_amount=546.87&t_amount_applied=0&t_amount_ope
n=546.87&t_invoice_status=&t_invoice=Y&t_check_key=4"><font
color="#FFFF80">Select Specific Invoice</font></A></font>
Man, I feel like I'm back in school learning PH Web; it's sooo different to
standard programming in PH4GL.
