Malcolm Here - That Code is now completely clean - record time to find 12+ Coding errors. TX V-Much for both your help and you demonstrations. Steping through code & into functions etc is great. After a day or two, it'll be the turn of the ASP debugger, and the the VBScript debugger. TX again MG

I've had a day or two now to play around with the SplineTech
JavaScript Debugger and I'm impressed with it. Just enter a URL and it will open the file
(and included JavaScript files as you step into them) in the debugger and load
it into IE. You can step thru the code, set breakpoints and watchpoints, and
hover over a variable name to see its value. ...the best
thing I've found. The price is very reasonable too... E-mail support is
excellent...
