How to add Item Weight to new tab in Item Maintenance

SOLVED

We have a client that would like to add the Weight field that is shown on the Main tab in Item Maintenance to a new tab he created.  I am not asking to move the field from the Main tab, just repeat it on the new tab.  I thought perhaps to create a UDF field to hold the value of the Weight field, but I can't seem to be able to do this either.  Has anyone else accomplished this?

Thanks
