I have a workbook (lets call it Filter.xls) containing several tabs with
different names, lets say: 111111, 222222, and 333333. The Filter.xls file
contains formulas which are applied to records of numerical data obtained
from separate works (lets call them Data1.xls, Data2.xls, Data3.xls, etc.)
containing several tabs with different names like 111111, xxxx, 222222, xxxx,
333333, xxxx. All aforementioned files would be in the same working folder.

What Id like the VBA code to do is to cycle through any existing
Data[#].xls files and check if there are matching tab names between them and
the Filter.xls file and, if so, copy the record set from the matching tab in
the Data[#].xls file to the matching tab in the Filter.xls file. I already
have code to copy the record set from the Data[#].xls file into the
Filter.xls file but what I am missing is the code that determines if there is
a match between the tabs in the Filter.xls file and any available Data[#].xls
file. If there is no match then notify the user and exit.

Id appreciate anyones assistance. Please contact me if you need further
details.
