VBScript Error

[cerruti1881]

When I ran my script, I got the following error:
TEST.vbs(583, 1) Microsoft VBScript compilation error: 'loop' without 'do'
I'm sure it's complete Do...Loop structure.
Within that main Do...Loop structure, there are couple of Do...Loop structures nested, each of them is complete. Some of them, it's got If Then Exit Do statement. Some of them, it's got Wscript.Quit statement. Do they matter? What could be the possible problem?
And, one more dummy question: Is there any free software that can run VBScript line by line for debugging purpose?

This is one of those occassions where, if you don't show us the code, we can't really assist.

>free software that can run VBScript
