Combining two workbooks

[WLMPilot]

Currently I have a BUDGET and PAYCHECK workbook. Each with sets of command
buttons. I want to combine the two the easiest way I can. I wish to keep
the BUDGET and copy the PAYCHECK format into the same worksheet for the
current budget year. The command buttons within PAYCHECK are to help
navigate within the worksheet/workbook, so they can be added easily if I need
to.

Is there a procedure to do this or do I simply copy & paste/paste special?

Thanks,
Les
