Yes, you need to have that function either in your workbook or another opwn
workbook or addin book. I have never seen this function. Ask the person who
gaqve you the workbook.

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!
