What is the best wording for a popup message that notifies the user that the value they just entered is a duplicate value?
The wordings I've considered are:
- The value you entered is already in the list.
- This value is already in the list.
- That value is already in the list.
Option 1 sounds the best to me; but my philosophy is that if you can get the message across just as well with fewer words, you should. Other than that, I don't see any obvious reasons to pick one over the others. Or perhaps there's another wording I didn't think of.
