Unable to get the correct total using the form calculation widget

I'm trying to do a very simple calculation and it's not working. (total number * 15). It is only multiplying by 1, and not 15. If I put in a "2" instead of 15, it works. I don't know why it's not working with 2 digits. 

Hello JanieFisher,

I checked your form and it appears to be working fine.

If this is not working as it should on your view, it would be great if you can share with us additional information on how you are viewing it and the type of browser you're using.

We'll look forward to your response.

Thanks.

Thank you, I kept working on it after I sent the message and eventually did something that worked. Thank you for your response. I didn’t know how to cancel this request for help so I’m sorry for the trouble.
