Calcs reset to zero using calculation widget

I'm selling three types of tickets. There's also a mandatory charge for postage IF the user requires mailout.

I'm using a checkbox for the postage BUT if the user changes their mind about postage after they've selected their tickets, the total due resets to zero (even though they have selected multiple tickets) and therefore, the value to be paid.

Is there a way to keep adjust the totals if the postage field is selected/deselected?

The Total Value was being overriden by the Calculation condition set in the Collection option (pickup or post). This is why the value becomes zero(0) when Pickup option get selected.

To fix, just remove that condition that update the value using the Condition.

Here is the test form https://form.jotform.com/60128675214958 were I removed the Condition.

Hope this help. Let us know how it goes.

Thanks.
