works but I really appreciate your help.

I have about 50+ worksheets in a file that I need to sum. However, I only
want to sum some of the sheets if it meets a certain criteria. This criteria
is located in a separate worksheet in the file that lists each worksheet name
in one column and in the next column it list the type of worksheet. If a
worksheet is of a certain type I need the sum of those types.
