Question about javascript in NBOS character sheet designer

LazyMaybe

Hello, I have a pretty specific thing I'm trying to set up on a character sheet using javascript.

I have locational damage in my system, and what I want to do is set it up so there's a part of the sheet that says
"I am taking [amount of damage] [damage type] damage to my [bodypart] : [button that deals damage]"
where [amount of damage] is a text field, and [damage type] plus [bodypart] are both text fields using lists.

So then the player could, for example, do:
"I am taking 11 slashing damage to my right arm", click the button, and then that bodypart would be modified in the correct way.

So, let's say the [bodypart] bit is a a text edit field using a list. How can I make what the list is selecting choose what text field the damage number is applied to?

There are of course several ways to do this, but one way would be calling a script function from a button with the source like
js:ApplyDamage()
and in the script tab define the function something like this

function ApplyDamage()
{
  switch(lstBodyparts.Text)
  {
    case "Head":
      txtHead.Text=txtHead.Value - txtDamage.Value;
      break;
    case "Torso":
      txtTorso.Text=txtTorso.Value - txtDamage.Value;
      break;
    case "Left arm":
      txtLeftArm.Text = txtLeftArm.Value - txtDamage.Value;
      break;
    // and so on
    default:
      // not found
      break;  
  }
}
