Ahh .. I see your point, but this is what I ended up with based on a few
earlier recomendations from Alexander
<CFIF IsDefined('Form.txtPaymentAmount#contact_id#') AND
Len(Evaluate('Form.txtPaymentAmount#contact_id#')) GT 0>
I don't believe, though, that your particular suggestion will work since I
am going through a loop on the second page to come up with the numbers .. it
kinda goes like this:
page_1.cfm
------------
<cfquery name="some_query" datasource="datasource">
SELECT primary_key FROM my_table
</cfquery>
<form action = "page_2.cfm">
<cfloop query = "some_query">
<input name="txtInput#primary_key#>
</cfloop>
<input type = "Submit" value="Submit">
</form>
page_2.cfm
------------
<cfquery name="same_query_as_on_page_1" datasource="datasource">
SELECT primary_key FROM my_table
</cfquery>
<cfloop query="same_query_as_on_page_1">
<CFIF IsDefined('Form.txtInput#primary_key#') AND
Len(Evaluate('Form.txtInput#primary_key#')) GT 0>
<!--- Do stuff --->
</CFIF>
</cfloop>
If I only test for #primary_key#, it will always be true since I am pulling
that value back from a query on the second page. This would be usefull for
telling me if a certain query row was returned, but doesn't really help to
tell if the box was filled on on the previous page, since I am, in essence,
looping with the same value I would be checking for.
