Forms :: Form That Adds Data To A Table Depending On Which Option Was Clicked In Combo Box?

i have a standard database with tblProducts, order, employees, customers, suppliers etc. i also have a table called tblperson with personID which acts as a one, with the many in three different tables (customers, suppliers and employee) the person table holds data such as first name last name address city postcode and phone. now, ive created a form called frmPerson that acts as a adding data to my database. ive got a load of buttons a working add, delete and a save button, i also have the option to switch through records next, last, end and first. now basically in this form i want to be able to add data i.e. fill out the text boxes and then have a combo box or something similiar that when i add the data i can basically click an option the says 'employee' 'supplier' or 'customer' and then the data gets added to my person table however the difference is that it will also be associated to the record in the wanted table.
