V8i VBA

I'm rather new to Microstation V8i VBA.  I am testing a toolbox with a user form that uses multipages.  It has several command buttons on each of the pages that call simple cad key-ins and other vba's.

An example:

Private Sub levOff_Click()
CadInputQueue.SendKeyin "levelmanager level offbyelem"
End Sub

The way it is supposed to work is you click the Level Off button, you then select the element for which you wish to turn off that elements level, and it turns it off.  The command is activating but it's not allowing me to select the element to be turned off.  When I try to select the element, I hear a ding thru my speakers and the form blinks.

This works when I'm not using multipages.  What am I missing?

The attached "PEC_Toolbox_Test.mvba" is using the multipage that is not working and the "PEC_Toolbox.mvba" is the one without and it is working.
