[AccessD] A2K: Pass Field Name to function

Hello all
The commented code below works fine.
That is if I type the FieldName in directly
What I want to do is pass in the FieldName from
passes parameters
I just can't get the syntax right.

Any help or suggestions would be most appreciated

Many thanks

Darren

        'Forms(stDocName).RecordsetClone.FindFirst

         'The line below fails whan I try and pass
the field name as a parameter
        Forms(stDocName).RecordsetClone.FindFirst
