hi frnds,
i had four drop-down lists,
1.field of study
2.subject(disabled)
3.country
4.location(disabled)
if i click on field of study the subject drop-down also in enable
condition.
i got it this.
what's my problem is if i click on counry drop down list i can't get
the subject drop down value. i got the all three values (.field of
study, .country,location) values ,but i didn't get the subject value;
here is my code.
@$cat=$_GET['cat'];
@$one=$_GET['country'];
@$subcat=$_GET['subcat'];
