Dropdown value mistake

HI,

Can anyone help me, i have a form calculation on the below form that isnt working

can someone tell me why?

When assigning dropdown values, the first value will be used for empty options, meaning if the dropdown is left empty and none of the options is chosen. I have checked your form, and it looks like you only have two options in your surveying tab:

What this means, is that "0" will be passed if the dropdown is left empty, and "10" if Not needed is selected, that's why when you select needed, it will break the calculation, because there's no value assigned to that option. To fix this, you only need to add "0" at the start of beginning of each dropdown values tab, like this:

This will fix the issue and your calculation will work perfectly, as below:

I have cloned your form and made the change, if you want, you can clone it to your account and start using it. You can do that using this URL:
