Joomla HELP with Listbingo and CB.

I have a website on Joomla that uses CB and Listbingo .... I have only One think uncompleted .... the Telephone number ... Here it is how i want it to be .. user FIRST TIME registers ... he press Post Ad ... and there he can input UP to 3 numbers ... the add is posted . Now these 3 number he had inserted there automaticaly are inserted in his/her CB Profile and now everytime he/she wants to post an add the number ARE already choosen (from the CB Profile). For better understanding you can have a look here ( [login to view URL] ) - you should register and try to post an add ... you will see EXACTLY how I want it to be. I have a budget of Up to 100 Euros !!! Hope you understand me ... Alex
