if value is Error/Bug show message

An error or bug is when something is not quite right.

 

if value is Abuse towards Staff show message

Abuse towards Staff is where another members has said something that was not needed towards a staff member.

 

etc... But i want it to show when they slect it and not when they change page. So it have to change instantly without refreshing the page.
