Hi everyone

I’m helping in a TV game project and the quiz show is a questions for 26 participants and you have a 26 pictures with 13 good and 13 wrong.

My problem is how to handle the information to everyone online which options is available when all the players are try to vote his option. The first player can take it but the second can’t.

How to check the update process if this options was already taken?
My first approach will be realtime database.
The player are at Android tablets and the info at Backendless table.

Thanks, Mario

Hi. It is not clearly for me what you want to do in backendless terms.
Are you trying to create a new db entry or update some existing row and get some kind of error?

Now the script of the TV game change and I’m working in Real Time Database.\

Thanks, Mario
