Question

I am trying to put some variable inside Variable Expression of another variable.
For example:

$V{sum} = $F{quantity} * ${price}, where sum is simple variable without any calculation
$V{total} = $F{disb} * $V{price}, where total has ‘Sum’ calculation type.

As a result I receive the wrong amount.

But If I use:

$V{total} = $F{disb} * $F{quantity} * ${price}

the amount is valid.

Is there any reason that variable inside variable expression gives wrong value? Thank you

If you are outputting the $V{total} of your first example in a textfield, then you will need to make sure the Evaluation Time is set correctly per your report. Most likely you will want to set the field evaluation time to “Report”.

The evaluation time determines when dynamically calculated variables are actually processed during the report’s generation life-cycle.
