External Links and Add ins
 

All -

I have created my 1st Excel Add-in.
I created it by saving my workbook as an .xla.
It seems to be working.

My UDFs create links in the ActiveWorkbook to the Add-in Workbook.

However, when I utilize UDFs from other Add-ins (like the Analysis ToolPak),
the use of these functions do not create a link. If I remove the Analysis
ToolPak from my Addin's list, the Analysis ToolPak UDF formula used in the
ActiveWorkbook just displays "#VALUE!".

Why does my add-in create links while other add-ins do not?
Do I need to save my Add-in in a different manner or change a setting when I
save it?

Thank you,
