In Excel 2003 how do I crate a temporary macro button at the tool bar or the top ba

Dear Sir / Madam

I am using Excel 2003 and I would like to add a temporary Macro button before the Help at the top bar or at the toolbar options.
I need this button to be visible without clicking any menu or other buttons.

Regards

Sami

Goto View>Toolbars>Customize
on the commands tab, scroll down the categories list to macros and click on it.
In the commands section, there should be a "custom button". Click-drag it to a position on a toolbar.
Close the dialog box.
Right-click of the custom button and assign your macro.
