Variable problems

I have this VBA routine I found that places objects onto a specific layer
depending on the object (i.e. Dimensions on the Dimension Layer, Text on the
Text layer, ...). The problem is that the variable that holds the original
layer does not get passed from the BeginCommand routine to the EndCommand
routine. Below is a copy of the whole routine. Could someone please point
me in the right direction? Thanks.
