I am trying to have a text field within my project be focused after a labels text prop has changed value. I am able to get the message handler to work with an "onClick" event but can't seem to get it to work on a prop change script.

Here is my code:

On the textbox I want to be focused

On Label's text property change script:

On buttons, "onClick" event (This one works, line 14 is the relevant one):

Any information would be helpful.

I tested `sendMessage` from a change script and it worked fine. Check your logs and see if any errors are happening before the provide focus line.

Also, you can change your script to be more succinct using `in`

```python
if self.custom.prgrm in (2,5,6):
    # do something

```

Also, you should use the `onActionPerformed` event for buttons, not `onClick`.
