When you did that, were you careful to remove all the "+" characters that had been inserted by PM's own code-line-wrap logic?

It looks like reneeb was not so careful about this, because that post includes  total += total +1 (where the first "+" had been added by PM line-wrapping).

BTW, "went nuts" doesn't sound like the kind of error code that I could look up and help you with. If you don't actually look at the content of the error report, and don't show us what it is, how do you expect to fix the error?
