Hi Lonkero, thanks for the response. I added the line as requested and ended up with the following:
 Code:
For $r = 0 to UBound($aResults,2)
	If $r > 0 
		? $c ' ' $r ' ' vartype($aResults) ' ' vartype($aResults[$c, $r])
		$UserDetails = $UserDetails + "," + $aResults[$c, $r]
	Else
		$UserDetails = $aResults[$c,$r]
	EndIf
Next


I ran the code and got the following output:
0 1 8204 8
0 2 8204 8
0 3 8204 8204
ERROR : Error in expression: this type of array not supported in expressions.!
Script: C:\Scripts\Kix\GetUsers.kix
Line : 32


Line 32 is the else line.

I then ran again with description moved to the second attribute rather than the fourth and got the following:
0 1 8204 8204
ERROR : Error in expression: this type of array not supported in expressions.!
Script: C:\Scripts\Kix\GetUsers.kix
Line : 32

Thanks for any help you can provide.
