Could be wrong, but this looks like it might be a user created function. I
have never seen this function.

I'm working on an Excel sheet for a client. When I open it, half the document
is full of #NAME? cells, indicating an unknown function. The root of the
problem seems to be the PICalcDat function. How do I fix this issue? Is there
some add-on I can install?

I use Excel 2003.

Thank you!
