At first thanks for all giving fast reply....... I posted the same question in ni forum but i got only one reply, here 5 replies. I think its a healthy forum to ask lab-view questions.
Bmoyer: Thanks for your vi. I like the way its working but what i need exactly is as said by hooovahh.
If you see in an original vi, it wont allow you to select two model at a same time.It indicates what model you have selected.If i press cancel in the pop-up message it will ask you to select the model.
I would like to create as same in the original vi..
