"Can anyone help me through this"

Not unless you give some details. 'Error while evaluating uicontrol Callback' is exactly what it says, there is an error in your callback, but you haven't shown us the callback or relevant code so there's not a lot more we can say until you do, other than the advice I always give, which is to use the debugger and especially the 'Pause on errors' functionality from the 'Run' dropdown menu.

In addition to what Adam wrote, this sounds like you want to have a table in your base workspace and want the table your GUI to change whenever you edit the version in the base workspace.

I would strongly discourage such a setup. If you insist, it is probably easier to have the table available as a class property.
