Hi Ben,
Sorry it’s not possible to repeat fields. But you can handle this with conditional logic like you have select option say:
1. one player
2. two players
3. three players
4. four players etc
And the you create input field
1. player name 1 (set condition if player 1,2,3,4 selected)
2. player name 2 (set condition if player 2,3,4 selected)
3. player name 3 (set condition if player 3,4 selected)
4. player name 4 (set condition if player 4 selected)
I hope it helps. If you don’t know how to setup this, we will do this for $25.00. contact sales@najeebmedia.com
