What I meant was I didn't understand the error message at all. I have only the vaguest idea what a resource is. So ms-its is like a variable name for "FWCalc:://Introduction.htm"??? Anyway, I tried a bunch of little changes but nothing helped. When I went back to my original code, the error is "... ms-its:FWCalc.chm:://Introduction.htm ...", so the ms-its has an extension. Maybe I forgot it in my original post. Sorry. Still, Help works; I just have to get past two error dialogs to get to it.
What am I doing/not doing that causes those errors?
