I have the following code, but I am able to prevent the form submit when the qty is less than the min bid amount but unable to submit the form when the qty is greater than min bid.

first time if input qty with a lesser value and then input the qty value greater than min_bid then the form is unable to submit.

If I input qty value greater than min_bid amount in the first time then I am able to submit the  form 

Please help
