Binding a text box to an expression

[Public]

Hi,
I want to bind a text box (containing a hyperlink) to an expression. I don't
want to include the field in the form's field list. I just want a way to be
able to bind the text box to an expresion. (btw my expression is taking some
values from the same form).
I have used Control Source propert but I only see "#Name?" in the text box,
any ideas?

Regards

Thanks but just to elaborate things. I want to display a field from a query
that is not the form's query (some external query) that is why I have to put
= sign at the beginning. Moreover, I have made sure that the Control Source
also doe not containg any spaces before = sign.

Any ideas?
