Hi Jonathon,
There's only one thisContact variable, which is being reused each time
through the loop. So all you need to do is put:
<cfset var thisContact = "">
right at the start. There's an indeterminate number of values that are
passing through that one variable on their way into the array, but it's
still one variable.
And of course var scope returnArray and q_Contacts as well. If you're on
CF9 things may a little different in that you may not need to explicitly var
scope, but I'll let the CF9 gurus pick that one up.
