Entry field is valid even if there is no visual character ( ''space'' key problem )


I am working on a course and I need to insert entry text field that allow users to type their names 

1- I inserted entry text field and button for submission ...

2- I added trigger that prevent submission if the entry text field is blank

I noticed that when i press "space " key ... i can submit it even if the entry field is empty

what can i do to prevent submission if there is no visual character in side the entry field


hope someone can help

hi wendy 

thanks for your response ... but the example did not work for me 

what i want to do is to prevent users from jump to next slide if the entry field is visually empty

- the blank trigger didn't work for me  , it considered ''space key'' on the keyboard'' as a letter; so ''submit button'' will be valid  if the user press 'space key ' only and that is the problem

also, if the user wrote her name inside the entry field and then delete it ... the '' submit button will be valid .

Hi Sofia!  I can understand wanting to make sure your users are protected from unintentional errors.  That's really thoughtful.

Just an idea:  Can you create a custom layer that will ask the user to try again when the user clicks submit IF the value of the TextEntry variable is a space?  

Obviously you won't be able to account for every errant keystroke, but maybe identifying a few common mistakes will help!
