A PHP Error was encountered
Message: Undefined offset: 0
Line Number: 133
Code Line : $GuNum = $this->encrypt->encode($ClubName['GuNum']);
hope someone can help with this
The error message is telling you that the array $ClubName does not have an array element with an index of 0 (zero). So now you have to debug to figure out if something is wrong with whatever populates that array, or if it's okay for that to be the case, in which case you probably should add some defensive code to not try to execute that command unless it is set.
