So, I have dozen of lines before that one and they all have the same oProcess.oApp.cCr at the end. I also tried to remove it. It didn't help.

One of the advices is to concatenate using & and not +. Did you try that?

Also your original message is really strange. You're saying that if you remove one character from the string .js you don't get an error? Is so, can you place just file name in a separate variable? Are you still having errors?
