Hi,

Firs of all, some coding knowledge is required in order to use wix-Code.
I suggest you to read about JS, starting with variables events and conditions.

Second, reference to the issue, you can add an onChange() event function to your both dropdown , and in each one add a condition that check if there is a value at the second dropdown, if true- update the total .
At my example the total text’s id is “total” ,
dropdown 1 his id is “dropdown1” .
dropdown 1 his id is “dropdown2”.
Here you can read about element’s event (the export functions) and ID.
Here you can read more about onChange() event.


export function dropdown1_change(event){
{ 
if($w('#dropdown2').value !== "" ){ //Means the user chose price in both dropdown
    $w('#total').text= $w('#dropdown1').value+ $w('#dropdown2').value;
     }
 }

export function dropdown2_change(event) { 
if($w('#dropdown1').value !== "" ){//Means the user chose price in both dropdown
    $w('#total').text= $w('#dropdown1').value+ $w('#dropdown2').value;
  }
}

As a result, each time the user choose an option, the total text will be update if in both dropdown there is a value.

Best of luck!
