Need help with simple(?) calculation please

Question

HelloI have an interactive pdf form where my simple calculation doesnt get the correct answer - sometimes no answer at all?A= number input by userB= number input by userV= A*Bso far so good, then:C= number input by userD= 0.8 1.2 3.5 (drop down list)     0.8 generates export value 0.7     1.2 generates export value 1.0     3.5 generates export value 2.3Q= product of C and respective exported value ------ this value is sometimes 0?T=V/Q*60  -----this is the final value which I never seem to get right

This is the calculation for T:var volume = this.getField("V")var flow = this.getField("Q")if (flow.value==0) event.value = "";else event.value = ( volume.value / flow.value ) * 60Did you check the field calculation order?

If Q is zero then you can't calculate a value for T, as division by zero is not allowed.

You must therefore use a script for T's calculation event, checking first if Q is zero. If so, apply an empty value to it.

If not, proceed with the calculation.
