Hello All,

I want to do some calculations on ERPNext/Frappe. Something very similar to Mathematical Formulas, Input two values, and third value will be calculated by the system.

to_be_calculated = {(ab / cd) + (ef / gh)} * 50

I’m very newbie in writing codes, trying to write but fails every time. What I’m trying to do is: *creating 4 new docfield*, which is *int/float*(I tried both), where *ab, cd, ef, gh is user input*. And, to_be_calculated is the value which *has to be calculated*, so another docfield for this, is *Read Only*. I’m adding these docfields in Item Master Itself.

But, nothing working. Can someone write sample script, to achieve somewhat similar, so that I can learn and use it.
