Erlang Run Time Errors

[oort]

Micheus,
Thanks for the additional information. That helps...

Unfortunately finding the right code to fix the problem with "toplevel" isn't as easy as I thought it would be. I have tried several things but can't get it right.

The code which includes "toplevel" is listed below. No hurry in you looking at this, since I probably won't be able to get back to it till next week...

Thanks,
oort
