hi, i'm new in here and i'm trying to develop a search engine like thing for a non-profit company, the company will import the contacts, make search amongst them. Now the point i got stuck is that, how to make those data fields active or in other words connect the data fields to each other. For example, I create a data field asking if the individual to be entered is a personnel or a student. There will be a single checkbox writing "Is this a personnel?", if this checkbox is checked it means he/she is else not, so what I want is that after this checkbox is clicked, a new data field to be opened for the personnel. How can I do it? Please help me if u can, I searched many places but could not find any answer...
