#### Simple Expression please help!

Greetings,

I'm trying to write a simple mel expression for my character rig, but each time i hit Create in the expression editor it says i have a syntax error in the last line (line 19.1).

Would anyone please be able to look at my simple expression and help me find what's wrong with it?

Thanks!

//check if there is rotation in Z
if(R_FK_Shoulder_CTRL.rotateZ != 0) {
// if there is rotation in Z, check if there is rotation in X
if(R_FK_Shoulder_CTRL.rotateX !=0) {
//if there is rotation in X after Z, then ik handle roll = rotateX / -2
AO_R_BendArm_ikHandle01.Roll = R_FK_Shoulder_CTRL.rotateX /-2}
// if there is no Rotation in X after Z, then Roll = 0
else {AO_R_BendArm_ikHandle01.Roll = 0}
} // if there was no rotation in Z in the first place, check if there is rotation in Y
else { if(R_FK_Shoulder_CTRL.rotateY != 0) {
// if there is Rotation in Y, check if there is Rotation in Z after Y
if(R_FK_Shoulder_CTRL.rotateZ != 0) ;
// if there is Rotation in Z after Y, Roll = rotateZ / -2
AO_R_BendArm_ikHandle01.Roll = R_FK_Shoulder_CTRL.rotateZ /-2;
// if there is no Rotation in Z after Y, Roll = 0
else {AO_R_BendArm_ikHandle01.Roll = 0} };
// if there was no Rotation in Y in the first place, Roll = 0
else {AO_R_BendArm_ikHandle01.Roll = 0};
}
