Hello all, 

A project I'm working on requires some string manipulation to write a name in the following format...

#####.###_yyyyMMdd 

The issue is with the . (Period) symbol. I can log the formatted text and it is correct; when the WF attempts to make the actual change to the field it drops everything after the . (period) and leaves me with  ####.aspx

I assume this problem is corresponding with some kind of special character limitation and I should write a symbol code instead. Does anyone know the solution?
