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}; } Last edited by takecake; 08-02-2017 at 06:36 AM.

There are multiple issues with the nesting of your conditions, as well as semicolons. Code: ```//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 }; }``` __________________ Imagination is more important than knowledge.
