>I have create student.dbf having fileds with 1.GE 2. MBC 3.SC 4.YA 5.KA and entered the values for GE =20, MBC =15 SC=10 YA =5 KA 7.
>all the fields are Integer type, and I have designed student.scx in that I have placed five text boxes namely 1.txtge 2.txtmbc 3.txtsc 4.txtya 5.txtka and one combo box and one command button. In initialisation event i have written code belwo
>use student

>I want two types of code
>1. I have selelct combo1.value = "GE" or "MBC" or "SC" then go to the GE field first and subtract the value -1, if GE fields value = 0 then if combo1.value = "MBC" then go to the MBC field and subtract the value -1 else, if combo1.value = "SC" then go to the SC field and subtract the value -1.

>2. But i have select combo1.value = "YA" " then first go to the YA field and subtract the value -1 else if I have select combo1.value = "KA" then go to the "KA" field and subtract the value -1. if 'YA" and "KA" fields value = 0 then go the "GE" fields , if "GE" field value = 0 then Message box there is no value.
