Call a function from a field on a form

[marathonlady]

Is it possible to call a function from a field on a form, ie, in the
control source put = FunctionName(abc)? Then I want to concantenate
it to another variable so it would look like:

=FunctionName(abc) & TextVariable

I tried this and got the ?Name on the form, like it couldn't find the field
name, which is really a function I'm calling.

Is this possible and if so, what am I doing wrong?

Thanks in advance for any help.

I just tested the function part: =FunctionName() in a text box and it worked. Must be the abc or TextVariable part...???
