combined drop down query result

hello
i have a couple of drop down list in my site
the ddl option connected to collection, and every time the user select one name of the list a query run to retrieve this name value from the collection and show it to him.
it works good whit on-change function for every ddl itself, but i want to be able to combine all the value from all the ddl together. i want the total to change whit every change of one of the ddl, not only to calculate it after the user finish selecting (that i know how to do whit the submit button).
so i need help :slight_smile:
thank

here my code so far (basic query for each ddl):

export function dropdown1_change(event) {

wixData.query( "players" ) 
  .contains( "name" , $w( "#dropdown1" ).value) 
  .find() 
  .then( (results) => { 

let items = results.items;
let item = items[ 0 ];
let price = item.price;
$w( ‘#text8’ ).text = (price).toString();

})
