In the stored below, I am trying to accomplish 3 things.
1, if a user attempts to sign up, check to see if the user has already signed up.
If yes, fire up a message that 'This user has already registered'
If not, then register the user with insert statement.
2, If registration is successful, fire up a message that says, "Registered successfully"
3, If registration is full, put users in the waitingList with INSERT into waitingList.
If registration into waitingList is successully, give a message, "You have been placed on waiting list"
None of this is working.
Your great expert assistance is greatly appreciated.
