Create macro to run linked table manager automatically

Brett Barry: Go Get Geek!

I am having problems trying to automate the refresh of linked tables.
I have two tables linked to Excel spreadsheets. Since these
spreadsheets are exported from different files in the same program,
they need to be refreshed just in case the user doesn't name the
exported Excel files the same and/or doesn't puts them in the same

I've tried to put in my macro the RunCommand LinkedTableManager, but I
wanted to make sure that the check box is automatically checked for
"Always prompt for new location."

I also tried this code I found, but I get a compile error when I run
the macro with a RunCode for the fRefreshLinks() function, "Compile
error: Sub or Function not defined" and it highlights this function:
Function fGetMDBName(strIn As String) As String and ahtAddFilterItem
in the following module (using Access 2007 with DB in 2003 format
already open):
