Yes.

What are you wanting us to do? Don't ask questions that can have a yes or no answer. We aren't just going to write the code for you either. What exactly have you done? Have you tried doing this yourself? I'll give you a hint, you will need to use either Number(), parseInt() or parseFloat() on the input from the form in order to calculate it.

So again what have you tried? We aren't here to just give you code especially since you haven't shown us what you have tried to let us know that you even are trying.
