how do I add action buttons in excel

[Guest]

I want to add a button that say"calculate", The user would click on this
button and a macro would run that would do the necessary calcualtions. How
do I get a button inserted into my workbook to which I can assign a macro.

Right click on any menu and select the Forms menu. From there select
the button icon and draw the button where you want it on the worksheet.
When you have done that a dialog will appear to assign a macro to the
button.
