What sort of combobox, and where is your module?

If it is a forms combobox, the assigned macro should go in a standard code
module.

If it is a control toolbox combo, you should check it the control's click
event.

I have created a module that will handle when a change occurs to the excel
worksheet in a combo box.

Depending on the selection value in the combo box, it will go to the
module
and change the format of the worksheet.

The problem is the module is not recognizing the combo box.

How can the module recognize the objects that are related to the
worksheet?
