Pb with TD

Hi
i tried to put this trigger in my version of Tower Defense :
*Player PLayer 1 (red) types a message in a chat message containing share 2 as exact string*
*Player PLayer 2 (blue) Turn units shared on toward player1

then i tried this one
*Player PLayer 1 (red) types a message in a chat message containing share 2 as exact string*
*Player Make joueur 2 (blue) as an ally with full units and vision shared*

i made this to resolve the pb of quitters and laggers BUT they dont work : each time i type share X the program crash (fatal error)

Why ? and how can i do ?
