I am trying to make additions or multiplications on my web site using wix code. I am an absolute beginner in this using infos got on youtube but I got error on the value part of the code I did (see below). Could you please show me what to do to make this code work!

// For full API documentation, including code examples, visit http://wix.to/94BuAAs

$w.onReady( function () {
//#labaguettefrancaise

});

let kgdefarine = Number($w(“#kgdefarine”),value);
let Qparpain = Number($w(“#Qparpain”),value);
let nbredepaindropdown = Number($w(“#nbredepaindropdown”),value); {
// Add
Qparpain = kgdefarine / 4.86;
console.log(Qparpain);
}

Thank in advance for all the help

You need a function such as a Button’s onClick event to do the calculation.

Below I have a Button with an id calculate

export function calculate_click(event) {
   let value = Number($w('#input1').value) * Number($w("#input2").value);
   console.log(value); 
}

The above function multiplies #input1 & #input2 and produces the result in the console.

Where is your button?

Select your button and screenshot the page to show the button’s properties panel

Sorry shan,
I do not follow you. as I said I am a total beginner in this, so you need to give me explanations for “dummies” if I can say so.
What I can tell you is that I gave an specific ID to each button
the 80 is dropdown1/#dropdown1
the 4 is kgdepate1/#kgdepate1
the button after 4 is qdepate1/#qdepate1
what I want is the it calculates me 4/80 & puts the result in #qdepate1 automatically which it doesn’t do.
reason can be that my button settings might be wrong or that my program has a mistake in it or is missing something make it work.
This is what I would love you to guide me though.

I thank you in advance for your helping me solving this problem which surely is an easy thing in the programing world but at this point it is a big issue.

Best regard

Stanley

you seem to be using commas in front “,value” instead of “.value”
