Re-use calculated outcome for other (editbox) calculation

[Jorus]

Is it correct that it is not possible to calculate a value for an editbox and automotically re-use the outcome/value from that editbox for another calculations for another editbox etc.?

This way I can easily copy paste a project to modify 1 value without having to rewrite all calculations..

Please see the 'simple_cart' example in the demo project.
Here the sum of 3 sub totals is used in the total field.

I've looked at it (formcalculation.zip) at the Simple cart page, but it only sum up the subtotals. In my case I'd like to implement my own formule/calculation (I don't have a typical cart system). I did try doing that using the Conditions/Expression window, there I implement my formule/calculation, where I refer to a Target (which is a subtotal too) but it doesn't work..

You will need to make sure that when the value changes, the other field's condition is also updated.
This can be done with the ''trigger change' action.
