How about --
<cfloop from="1" to="#form.looplength#" index="i">
<cfoutput>
<!--- concatenate the 2 values --->
<cfset temp1 = "form.cat_id" & #i#>
<!--- then evaluate the concatenated expression --->
<cfset catarray[i] = evaluate(temp1)>
<cfset temp2 = "form.subcat_id" & #i#>
<cfset subcatarray[i] = evaluate(temp2)>
<etc.>
I got something similar to work for me just today, though I wasn't using
arrays.
