How to calculate the sum of the row inputs in configurable lists widget?

I have a form where people are evaluating multiple musical performances.  Some will just be listening to a few, some listening to many.  For each performance, they have to fill out a line of a "list" with a drop down menu to select their score.  Is there a way to have this automatically tallied in a separate column?    For example, see the form I have linked below.  It should be active.  I just want the column that says the total to actually be automatically totalled...

Thanks

Hello,

I would like to apologize that this is not possible within JotForm. There can be a workaround to pass the value of the first line entries to be summed up but since you have an add button, the newly added rows will be hard to summed up into another field.

If you have limited number of musical performances, you may try to add all the performances that will be evaluated on your form, and try to add calculation for each of them. In this case you need to use basic form elements instead of list widgets. Widgets are so complex and dynamic that it is hard to get values from them and perform calculations with the inputs.

I hope this answer helps. If you have further queries please contact us again.

Regards.
