How does one determine if a control (button) on a command bar (toolbar) is visible or not so it can be acted upon for an IF...THEN statement?

This bit works if the control is visible:
Visible = Application.CommandBars("PivotTable").Controls("Re fresh All").Visible

If the control is not visible then I get the following error:
Run-time error '5':
Invalid procedure call or argument

TIA!
