Hello,
You’ll need to use something like a javascript expression to change the value of the variable used in the dropdown select. You could use a switch statement. For example:

var dropdownValue

switch ($data.value) {
     case ("selection1") :
         dropdownValue = "p1";
         break;

     case ("selection2") :
         dropdownValue = "p2";
         break;
     
     default :
         dropdownValue = "p3";
}

return dropdownValue;
