RM Rule not Functioning

Hi All,

Can I get a hand,

Have a rule im RM that is having an error, which is causing it to work intermittently

Here is the rule

Here is the log for it showing an error

Thank you for the help

Just a guess: what is the switch "Morning"? Does it turn on Morning mode? If so, you are probably running two instances of the rule simultaneously, which will often cause problems (the fact that the error in question is a ConcurrentModificationException supports this guess, but without knowing more that's all I can guess). In case it isn't apparent why this is happening, it's because you also have "Mode becomes Morning" as a trigger. Figuring out some way to eliminate the simultaneous execution would ultimately be the fix, and how depends on your goals.
