Well this is my dilema,
I created a form to enable a verification team take less time in the field. I want them to be able to type in a unique number (in this case a "subscriber number"), then they will have to press a button ("Update" button) to query the database whether the customer details exist. This button will have to link to a database file which will automatically fill the rest of the attributes. this number will act as a link to call query the database file whether the customer exists or not. If the customer is absent, the data entrant should be prompted to fill in the details. (Take look at the snap shot)
NOTE: am using ArcPad 10
