  //Data from THIS LAYER > Position > "X" Only
center_X_con = 7.2 ;
center_X_var = pickwhip ;
left_X_con = -242/8 ;

  //Data from THIS LAYER > scale
  scale_X_center = 100 ;
  scale_X_var = pickwhip ;
  scale_X_side = 37/3 ;

  //THAT'S IT! I'll take it from here
dist_pos=left_X_con-center_X_con;
dist_scale=-(scale_X_center-scale_X_side) ;
center modif=math.abs(center_X_var-center_X_con);
x=scale_X_center+((-center_modif'dist_scale)/dist_pos) + (scale_X_var-scale_X_side) ;
[x,transform.scale[1]]

  it seems that

  center_modif'dist_scale

  should be

  center_modif*dist_scale

  You should delete the spaces before “;” And try turning X’s into lowercase, and “m” from Math to the uppercase.

  dist_pos=left_x_con-center_x_con;
  dist_scale=-(scale_x_center-scale_x_side);
  center_modif=Math.abs(center_x_var-center_x_con);
  x=scale_x_center+((-center_modif*dist_scale)/dist_pos) + (scale_x_var-scale_x_side);
  [x,transform.scale[1]]
