CoSMOS Gamehacking Tool

Hi all--Fairly new to all of this so please be gentle, I've downloaded a table for Cosmos but I can't activate it no matter what I try. I'm sure I'm doing something wrong but every time I try to activate a cheat it a red exclamation mark pops up and the cheat won't work.

What am I doing wrong?

Mouse hover the red exclamation mark, what does it say?

"Error in line 34 (nop3) The instruction cannot be complied"

The line number changes but the rest stays the same when I try the other cheats

Instead of nop3 can try to change the script there to:
nop
nop
nop

OR

db 90 90 90

Or add a space between nop and 3: "nop3" => "nop 3".
