No question is dumb, and don't ever feel that way. Every one on here had to
start sometime.

There are 3 areas in the Insert|Name|Define.
Enter the name of the variable in the first line right below Names in
Workbook:
Then, in the Refers to: field, clear out anything that might be in there,
and type in the formula that I gave.
click Add on the right hand side, and then the name should appear in the
space below that first line.
