Auto Populate Fields on Form

Auto Populate Fields on Form

Ok so I have a table with 8 columns. I have a correspondng form that has 8 fields which correspond to the 8 table columns (Field 1, Field 2, Field 3 etc..). The first field ion the form is a pull down. I want to make it so that when I chose a record from the pulldown in the first field, the other 7 fields auto populate the corresponding data from the table. For example, the first field in clients name and the other 7 fields contain contact info. When I choose a clients name in the first field of the form, I want that particular clients contact info to automatically populate in the other 7 fields. Please help!
