Attached is my Address book where user input Address and
Attached is a screen shot of another website correcting a address after being imputed.
I believe the software is a api ( not sure ) and have found the download on the UPS Website.
IF you have doens this before then it would be even better.
I need this installed on two place in the website. ( address book and popup address book )
I will need that suggestion pop up window with artwork included.
Thanks so much.
