It IS possible to edit/delete game info that you have entered while scoring a game, but only after each quarter. When you finish scoring a quarter, you need to press the little number in the very right-hand side of the page (next to the score for each team) to take you to the next quarter. When you do this, a summary of the quarter you just scored will appear. You will be able to edit or delete any stats that you had previously entered. Once you have saved a game (at the end) you will no longer be able to go in and edit or delete the game.
PLEASE NOTE THAT YOU CAN EMAIL SARA@AZEVEDOWATERPOLO.COM TO REQUEST THAT WE DELETE YOUR GAME/S FROM OUR BACKEND.
