How to create a confirmation box that changes the state of a form

[kartikey]

Hi Everyone, 

i wish to create a confirmation box on submission of a form that asks if you wish to change the state of the parent case to work in progress.
it should simply ask 'do you want to resume the case' with two options yes or no, if i select yes the parent case of that form should change it's state to work in progress, and if i select no then  nothing should happen and it should simply submit the form.
Does anyone know how do i achieve this?

Thanks,
kartikey
