Paste Userform textbox values into next empty cell on a sheet

Hi guys,

Getting stumped at the last hurdle here. I want to copy three textbox values (RegisterID, ContactDate, BillingCode) into the next available blank row on a worksheet.
I have worked out getting to, and selecting the first empty cell in col A on the row (example cell A9). Icannot work out how to paste RegisterID into A9, ContactDate into B9 and BillingCode into C9!
Can someone help? Code so far:

        
        Sheets("Billing").Select
        Dim NextFree As Long
        With Sheets("Billing")
                NextFree = Sheets("Billing").Range("A" & Rows.Count).End(xlUp).Row
                Range("A" & NextFree).Select   '[A9] for example - works to here
                'A9 needs to be Userform's CboPatient.Value
                'B9 needs to be Userform's ContactDate.Value
                'C9 needs to be Userform's PNCD.Value
        End With

Thanks in anticipation!
