I tried this method, the looping *seems to be working*
<cfscript>
For (i=1;i LTE Form.PE_Counter; i=i+1)
if(StructKeyExists(FORM,'play_#i#')and
Trim("Form.play_#i#") IS NOT ''){
session.NODA09_formStruct.play_[i] = form[play_[i]];
<----- error is in this line
}
</cfscript>
However this code throws the following..
You have attempted to dereference a scalar variable of type class
java.lang.String as a structure with members.
When I start playing around with the bracketing, it starts throwing CF
errors...
