多目标拓扑优化设置问题？

*** ERROR # 1614 *** Syntax error in DEQATN # 1. The number of left parenthesis is not consistent with the number of right parenthesis. 有没有大神帮忙研究下这个错误。以下是报错的公式F(x1,x2,x3,x4)=rss(0.198/7814.435*(x1-74.15),0.198/18165.98*(x2-121.98),0.198/5948.906*(x3-32.96),0.24/873532.5*(3518987-x4)) [图片]
