Teaching magic spells through weapons

Yes Angelo's and my code is correct. After leveling up Lenna with the Mythril Shield supposed to be teaching Fire 2, it worked. My computer doesn't have access to Imageshack but Lenna DID learn Fire 2 from the Mythril shield after the fight. AP was shown as well.
$1DD1, Bit 3 IS the correct event bit for granting magic points. $43 is it's number in hex following the $B8 command. Also look ahead at the third byte following the $43 and make sure there's nothing conflicting it's execution.
Not sure why Leno said the parameter was wrong at all. This worked perfectly from my tests.
