[proFit-list] tabulating fits with more than one output

[Chris Lee]

I am not sure that I understand correctly, but let me check. It sounds  
to me as if the first fit works properly and generates a table and the  
second fit fails? If that is the case, it may be that the act of  
tabulating the values is changing the active table and/or columns.

When you perform a fit, the sheet gives you the option of choosing the  
data window, xColumn, yColumn and other options. Are these options set  
correctly on both occasions?

Cheers
Chris
