HI dependent drop down is not working after referencing!! and imagine every column is dependent on each other like roll no is dependent on name &class dependent on roll no and subjects dependent on class.

Any sample apps??

For example consider an app called school there are two tables BASIC INFORMATION & ACADEMICS in basic information columns be like NAME ROLL NO in ACADEMICS columns be like CLASS SUBJECTS and i want dependent drop down for NAME, ROLL NO, CLASS, SUBJEC...
