If...Then Statement Trouble *RESOLVED*

[twisted]

How do I get this If...Then statement to work only when a radio button (radCheck) is checked?? Here's my code..

If txtTransaction.Text > txtDeposits.Text Then
                MessageBox.Show("$25 service charge applied.", "Insufficient Funds Penalty")
                txtCharges.Text = (CH).ToString("c")
                txtTransaction.Focus()
            End If

It is doing it everytime, but I only want it to execute if radCheck.Checked
