calculate result triggered by selected fields

[Ian239588556wr0]

Hi, I need to calculate a result in PDF form. I have 5 fields: kg, lbs, result, quantity and ml.

The formula for result is event.value = Number(this.getField("kg").valueAsString) * 1.8;

> for this formula the user could enter a value in either "kg" or "lbs"

If the user enters the value in "kg", I want the "lbs" to automatically populate and vice versa.  

calculation is "lbs = kg * 2.2" or "kg = lbs / 2.2"

The formula for quantity is event.value = Number(this.getField("result").valueAsString) / 50;

The formula for ml is event.value = Number(this.getField("result").valueAsString) / 5;

How can I make this ?

What should happen if they fill in both the "kg" and the "lbs" fields?

@try67 

if I enter 50kg the lbs field should show 88.

If I change 88 to 110 in lbs the kg field should update to 50, etc. (based on the calculation)

As the custom Validation script of "kg" enter this:

this.getField("lbs").value = (event.value) ? event.value * 2.20462 : "";

And as the custom Validation script of "lbs" enter this:

this.getField("kg").value = (event.value) ? event.value *  0.453592 : "";

[Edited: values were reversed. Thanks, @Nesa Nurani ]

@try67 Ok for these that works, but what would be the script for the "result' field to pick either "kg" or "lbs" ?

[try67]

It doesn't matter, since the values will both be the same. Just choose one and use it.

[Nesa Nurani]

2.20462 should go in "kg" and 0.453592 should go in "lbs".

[try67]

Sorry, yes, will fix now...

last thing. I need to limit the "result" to be no higher than 180

[try67]

Add this to the end of your calculation script:

event.value = Math.min(180, event.value);
