Pretty new here and still learning and testing the tool but here is my suggestion:
Bind Label A value to a pageVar ‘labelA’ so that value 21 be stored into that var.
Bind label B to another pageVar ‘labelB’, and set its value as a formula with something like pageVar.labelA*0.33
Thanks Fred, I changed the input field to a text component, but I still cannot make the formula work,
The formula is applied to a text field and the idea is that it looks at what is in the input field above assigned to var A and first calculate 40% of it and than make sure it rounds the number down to 0.5
When I type the formula like you did I get this error
Thanks Bravo, but this will also round to numbers like 5.6 and 5.7 etc…
The idea is that the numbers I will use are weights, and the smallest weight I have is 0.5kg
so if the calculation says I need to use a weight of 6.74kg the round formula needs to show 6.5kg,
if the calculation was 6.76kg than the rounding needs to go to 7kg
I hope it makes sense, I don’t know if this is even possible.
