[Script] XSE Error: "Type Mismatch on Line 21. Missing #define"

[AbsoluteJustice]

Don't want to keep bugging the community but this one's got me stumped, because I really can't see what's wrong with the script. I put it in the Spoliers box and pointed out Line 21.

Spoiler:

#dynamic 0x800000

#org @start
lock
faceplayer
checkflag 0x200
if 0x1 goto @done
msgbox @1 0x5
compare 0x800D 0x1
if 0x1 goto @take
msgbox @2 0x6
release
end

#org @done
msgbox @3 0x6
release
end

#org @take
giveitem 0x4 0x1 MSG_OBTAIN THIS IS LINE 21 BTW
msgbox @3 0x6
setflag 0x200
release
end

#org @1
= Do you plan on catching any\nPok?mon ahead?

#org @2
= Suit yourself. \pAnd here I was ready to give out\nfree Pok?balls...

#org @3
= Did you know Pok?balls have variants? \pGreat Balls and Ultra Balls are\njust a couple of 'em!

Very strange. Happens when I try to compile it btw

Seems like you may be missing the "std.rbh" file that contains the original definition for the variable MSG_OBTAIN, which is, by default, 0x0.

Either investigate the std.rbh file in the same folder or try changing 'MSG_OBTAIN' to '0x0'.
