"The formula field isn't valid." when doing a CRM import

Hi, 

I'm getting the attached error when attempting to do an import from Dev to Test. I've stripped everything out, and have no changes ... only the existing Entity and then I Export -> Import and get this error.

I've also included the XML log file ... and as you can see it doesn't say which field is giving me grief. It refers to "s137" but I don't know what that means.

Does anyone have any advice? I've search this forum and others and tried all the solutions given. 

tia,

Rodney
