insert contacts

[ankycooper]

[img src=\"style_emoticons/[#EMO_DIR#]/unsure.gif\" style=\"vertical-align:middle\" emoid=\":unsure:\" border=\"0\" alt=\"unsure.gif\" /] I have a database of contacts with their information(name email, address phone ,fax...)
now i have a billing form which will have all the feilds mentioned above plus some billing feilds
now what i want is that there is a insert button on this page which opens up the contact page(pop up) and u can check a perticular contact and submit so that all his info comes to the respective feild in the main form

Please help
