Matrix not calculating in Form Calculation widget

Hello, I am working on putting together a fairly complex registration form. I have made several input/matrix tables, using radio buttons, with calculation values for every cell in every matrix. I am then using form calculations widget to calculate the total number from the matrix. I followed https://www.jotform.com/help/343-How-to-Perform-Form-Calculation-in-the-Matrix-Field to set this up.

Before I even started adding multiple tables together I wanted to test the calculation of one matrix together, in the "total for all adults" form calculation section of page 2, however it is not calculating at all. Can you please let me know where I went wrong?

Thank you!

Hello, I have checked the form you shared. The calculations seem to be fine. 

But, I suppose that you are using the 'Fill Form' option when testing. I am not 100% sure why, but this is not the right way to check widgets, sometimes user action is required. So, I have tested your form manually and got correct results:

However, you can remove the last "+" to be sure:

We will gladly assist if you need more help, just let us know.

Unfortunately the "Total for adults" calculation is still not working. As you can see below I have set up all the others and they are working fine, but not the adult calculation. I did not use auto-fill, I did everything manually. 

That field has few extra plus signs:

So that is the reason why it is not working.

Please remove them and check if the issue persists.

Thank you!
