Ok,the problem i guess is here:

C#

else if  ((((ChkCleaning.Checked == false) &&
            (ChkXray.Checked = false) && (ChkCavity.Checked == false) &&
            (ChkFluoride.Checked = false) &&
            (ChkRootCanal.Checked = false) &&
            (ChkOther.Checked = false))))

If you look closely, you can see that some of the clauses have an assigment operator(=) instead of an equality operator(==). Change that to:

C#

else if  ((((ChkCleaning.Checked == false) &&
            (ChkXray.Checked == false) && (ChkCavity.Checked == false) &&
            (ChkFluoride.Checked == false) &&
            (ChkRootCanal.Checked == false) &&
            (ChkOther.Checked == false))))

and I think it should work.

P.S. Debugging is your friend. Don't forget it :)
