VB compiler does not recognize VB functions.

[dominja]

VB compiler does not recognize the Vb String function yielding a "Can't find
project or library" error.

 

[Dave Peterson]

Open the workbook with the problem
Go into the VBE
Select that workbook's project
Click on Tools|References, look for a MISSING reference.

Delete it or replace it with one that you need.

Missing references can cause errors that have no relationship to the line that's
marked as error.
