a few things:

text event inside of another

on *:TEXT:!gto:#: {
  .action Go's to Hell.
  .msg $chan What now, ( $nick )?
  on *:TEXT:*:#:
  .msg $chan Yea.. I didn't think $nick had anything else.
}

and even if that one was fixed, the text event that is inside, would be triggered on every channel message sent.

missing "If" statement

on *:TEXT:!AttemptHelp:#: {
  ( $7 = !AttemptHelp ; !AttemptStart ; !AttemptHell ; !AttemptList )

and i think he is using : as "or" which should be || but even then i dont think the coding is right. also, a little explaination of what people should type for the commands would help, considering your script is checking for the seventh word.

and this last section, not only is missing brackets
but even once fixed, one of these text events would trigger on every channel message with 3 words or more

on *:TEXT:!HellSing:#: {
  If( $2 = $nick )
  .msg $chan /-\WARNING!!! ( $nick ) Has Requested that HellSing Be Turned On!!!/-\
  .msg $nick the HellSing System is ON.
  .msg $chan (-^HellSing System OnLine.^-)
  .msg $chan Welcome To Hell.
  .msg $nick To turn off HellSing, Type !HellSingOff
  on *TEXT:!HellSingOff:$2: {
    .msg $chan ( $nick ) Has Turned HellSing Off.
    .msg $chan (-^HellSing OffLine.^-)
    if ( $3 = !Hell )
    on *:TEXT:$3:#: {
      .msg $chan ( $nick ) Has Used the (~HELL~) Command.
      .msg $nick You have Activated the (~HELL~) System.
      .msg $chan (~HELL~) OnLine ( Authorized By $nick )
      .action 04,01UnLeashes Hell.
       }
