Calculation in row-update widget

Within an event, can a calculation be used for the value of the field being set. For instance, can I add the value of two fields together (i.e., dataview.field1 + dataview.field2)?

If this can be done, what is the proper syntax and would I use the “value” field or “Expression” field to enter the calculation?

I know I can use a function and set the value to the output of the function, just wondering if the more direct approach is possible?

Thanks

There is a calculator widget in app studio that will handle this.

Thanks Alex. I will give it a try.
