Do I need to have a multiplier?

Do I need to have a multiplier?
Mine is a list of foods with a price next to each - customer can pick one or many options of each line, but not multiple of the same line.
Calculator currently stays at zero - is this because there is no multiplier?

Hi Brian,

Thanks for reaching out to Jotform Support. Can you explain a bit more about the issue so I can get a better idea of what's happening? If you can take a screenshot of what’s happening and send it to us, that would help us understand the issue. This guide will show you how to do that. 

Once we hear back from you, we'll be able to move forward with a solution.
