I keep getting an error message when I run my game

run-time error '9'
subscript out of range

Can anyone tell me what this means and how I might go about solving the problem?

More generally is there anywhere in the manual, or anywhere online that I can look up errors and find some information?

have Error Log enabled, or click yes/ok when it asks you if you wanna view the error log. then just copy and paste everything in that box on here and we/i will help you sort out the problem 8)

A run-time error message box means something has gone wrong in Quest. It may be that a mistake was made in your ASL file, but when that happens Quest should be checking for it and printing a message telling you what's wrong. So, whether there's a problem in your ASL file or not, there is something wrong with Quest.

If you could send me your ASL file (email me at alex@axeuk.com) and tell me which version you're using, I'll take a look into it for you.
