I can't seem to figure this one out.

I have a sheet per check date and a summary sheet. In "check date" sheet,
there are two columns, A=check amount & B= check mail date. There can be
different amounts of rows per "check date" sheet.

On summary sheet, I want the total checks mailed on by date. This will
cross several "check date" sheets.

I can do it using just one sheet, but I don't know how to add the other
ranges.

Please help.
