Problem #1) The ON TEXT event doesn't have a location identified. The options are # for a channel message, ? for a pm/query message, or * for channel or pm/query message.
Problem #2) The alignment of your braces and the ; characters. The ; is treating parts of your code as remarks.
Here's a re-write, and as long as you're going to remain small for the number of help lines, the general format that you have is fine.
However, if you think or find that you're needing more lines, I would suggest putting the text of the help lines into a text file, then using the /play command to send the text file to the nick that used the !help command.
For more help with this, see /help /play
Here's a re-write with the errors I found corrected (and some spelling errors corrected as well)
