Programmatically changing the "message" for the express VI prompt user for input

[Robert Stephen]

I was setting up the express vi "prompt user for input" and wandered if it was possible to programmatically change the message like the "Display Message to User".
I tried converting to a sub_vi and adding a control, wiring it to the indicator, hiding the control and adding the input to the connector but it doesn't seem to do anything.
Any suggestions?

Sorry, sorted it. Just noticed a property node reinitializing all the controls and indicators to default values happening after I changed the message. Correct execution order has now stopped this
