I split this off to a new topic from your other thread; I'm happy to show you this as well!
The reason why your message continues to display is because there is no change back to FALSE if the formula is untrue. Instead, a way that would work would be to set the value your
$[Mesaje] variable to the formula you wish to evaluate, and set
$[Mesaje] as the the visibility formula of the message's content box. This is how it would look:
I created a variable called
$[ShowMessage], which checks if there is already an item in the Items Table with the entered name:
The formula is put under the data tab as shown below:
The content box with the message has the value of that variable set in the visibility properties:
I also created another button that is greyed out, which you can then show if the item already exists (which does not have any automations; it is unclickable).
And the blue button with the automation displays if the item does not exist yet, allowing the user to add the item:
Hope this helps! Let us know if you have any other questions.
