Need to link drop down list from range in xlsm (Add-In)

Dear All,

I need to link drop down list from range that saved in xlsm (Add-In). I could able to link it to lookup formula but in Data Validation I couldn't do it.
Lookup example:
B1 is =VLOOKUP(A1,My_ADDINS.xlam!MyRange,2,FALSE)
Where My_ADDINS.xlam is the Add-In, MyRange is the range.

I tried to use the same method in the source of the Data Validation as follow but it didn't work with me.
=My_ADDINS.xlam!MyList
where my MyList is the range name saved in the My_ADDINS.xlam file.

Any one can help please.

Thank you

the problem might be that they are not part of the same file/project... you can easily import the data from one file into a sheet in the other workbook tho... that's just a simple copy/paste routine in VBA

import it, process it, and then delete it

have you tried testing it with both sheets in the same book?

VLOOKUPs really suck

Try creating a defined name in the workbook with the data validation that refers to =My_ADDINS.xlam!MyList and then use that new name as the DV list source.
