Forms: Field values are adding even when deselected from form

I have created a cake order form which calculates the costs depending on which options are selected.

When an option is selected, and then deselected and a different option is selected, the form does not reset. Instead the sum of both options are added together.

Hello Robyn,

Thank you for reaching out to Jotform Support. I cloned your form to test it, and I easily replicated the issue. There’s an easy fix for this. We just need to set the form settings where if the fields are hidden, the value is also deleted. Here’s how to do it:

1. In Form Builder, in the orange navigation bar at the top of the page, click on Settings, and then click on Show More Options.
2. In the Form Settings menu, scroll down and select Clear when Hidden in the Clear Hidden Field Values. 

Give it a try and let us know if you have any other questions.
