Command Button Issue

[James]

I have a form where by I have 3 cboboxes on it...

These have the follwoing values:

cbo1 (Male,Female)
cbo2 (Q01,Q02....Q25)
cbo3 (True,False)

I have a query which calculates the percentage in the
database based on the values of them cboboxes.... so it
gets the percentage of the total number of records by how
many of the values in them cboboxes...

I would need my text box to pull up that percentage from
the query based on what is in the cboboxes.... So if they
change I would need the text box to be updated when all
the values have changed and maybe a calculate button
pressed?

IS this possible?

Many Thanks for your time and effort

James
