Add One To Database Recordset Data

I’m in the middle of designing a simple website poll... nothing to fancy a simply question and results type thing... however I’ve hit a problem in that I cannot figure out how to add one to the running total when a vote is cast. For example:

Do you like this website:

A: Yes Lots – radio button if selected adds one to yeslots column
B: It’s ok - radio button if selected adds one to Itsok column
C: It could be improved - radio button if selected adds one to Itcouldbeimproved column

And of course we’re using an Access database for this one.
