What kind of dimension is a ribbon?

[RandomGerman]

Hi there,

a few weeks ago Paul taught me how to make my tab the active one (thank you!), using:

Sub OnRibbonLoad(ribbon As IRibbonUI)
    Set oRibbon = ribbon
    oRibbon.ActivateTab ("MyTab")
     
End Sub

This used to work fine, as long as I didn't use Option Explicit. Now debugging asks what kind of variable "oRibbon" is. Can anyone help me? Thanks in advance!

RG

btw: I use 2010.
