Possible to get input validation as user fills out PowerApps form?

Hi everyone,


I was just wondering, is it possible to get input validation as the user fills out the PowerApp form? My form is connected to a SPO list. Just to clarify, input validation is working when the user tries to submit the form, and if there are errors, the user will be prompted and the form won't submit. I was just thinking it would be nice if say, immediately after the user inputs an incorrect value, they would be prompted as soon as they switch to the next field.


Also to provide more information, the valid input range is numbs from 0 to 24.


Thanks so much for your time!

Have you tried the Validate() function? You could use it with the OnChange property to set variable and the use the variable to display the error message in another field.
