Excel 2007 : Data Input Form

Hi to all who read this

Basically, i am trying to learn VBA but my head hurts in trying to phathom out codes. I have put together a userform (attached) and i have no idea where to start with the code.

Is there some kind soul out there who can show me how to get the user form to function.

Its a data entry form for filling in a new customer. The new data will then be submitted to the Customer List worksheet.

Any help to get me started would be much appreciated.
