Here's the situation, the follwoing script works with three combo boxes, when I attempt to add the forth it generates the following errors, from the Netscape JS Debugger

Line 1591
thirdGroup[j] has no properties

(there would be 1994 lines with all the arrays populated)
The arrays are populated with a Cold Fusion Script.

haaaalllllpppppp!!!!
