Combine (3) Workbooks to Master Sheet

Hi,

I am looking to combine (3) Worksheets from different Workbooks onto one Master Sheet.

I would be looking to combine the "Combined Shedule" Worksheet on all (3) attached Workbooks to create (1) Master Schedule.

All of the workbooks would reside in the same folder (the folder also has other workbooks in as well).

Hoping someone can help?

Thank you!
Sandi
