Validate a screen entry through message

Moderator message: do NOT offer points

Dear experts,

I have designed one screen containing 10 entries of 10 different fields.

One entry is for amount . I want that amount to be less than 1000.00 and if it is not so it should give message.

My logic is working fine..but the only problem is that when I make a wrong entry , it should allow me to corrrect it there and there only..

now with message type E , it disables all the fields and other entries are also to be entered again...

and with message type W and I , it is taking that as a right entry.

So which message type should I use ? Or any other alternative ?
