Confirmation on numeric text field

I would like to add a confirmation before fire up a numeric text field
I add some scripts on property change but does not work as I expected

if system.gui.confirm(“Are you sure you want to open this window?”):
if event.keyCode==event.VK_ENTER: event.source.doClick()
return

would you please help me? numeric text using an indirect tag to UDT parameter

Vision, or Perspective?

Vision

propertyChange events happen after the property has already changed. You could add a custom property with the ‘real’ value, that you only write from scripting after your write has been attempted from the text component itself.

Thanks for the reply, I tried several ways, but I didn’t get results, do you have any examples? Confirmation of any input should be a basic part of SCADA

Can you advise a quick example on how it is done?
