Excel "IFS" statement equivalent in Forms

[symone_1736]

This is what I'm trying to accomplish:

- CHOOSE ABC DEALERSHIP FROM DROP-DOWN LIST TO POPULATE TEXTBOXA

- TEXTBOXA HAS CALCULATION SCRIPT: var TETXBOXA =this.getField("DEALERSHIP").value;
event.value=TETXBOXA;

^^ this portion works great. Here is where I need assistance:

I NEED TEXTBOXB TO BE THE ADDRESS OF WHATEVER DEALERSHIP TEXTBOXA IS.

Use a validation script at the dropdown for all text fields.

You can use something like this as validate script of TEXTBOXA:

var dealers = {
  "Dealership1": "Address1",
  "Dealership2": "Address2",
  "Dealership3": "Address3",
  "Dealership4": "Address4",
  "Dealership5": "Address5"
};

var d = event.value;
if (dealers[d]) {
 this.getField("TEXTBOXB").value = dealers[d];} 
else {
 this.getField("TEXTBOXB").value = "";}

Be careful with field names, in your post you wrote TEXTBOXA but in your script is TETXBOXA.
