Solved: Show text from textbox on worksheet in textbox on userform

[ceeejayy]

In Excel, there are:

1) A text-containing Autoshape Text Box ("tbWorksheet") residing in a Worksheet .
2) A vba object textbox ("tbUserForm") residing in an attached UserForm.

I wish to link tbWorksheet and tbUserForm such that text in tbWorksheet appears in tbUserForm.

I have tried various linkages utilizing control source property, tb__.Text, tb__.Value, etc but can't make it work. Tr?s frustrant.
Any assistance is greatly appreciated. Thanks in abundance.
