以下是代码：
qui reghdfe CliqueOwnership c.IC_Shock#c.Treatment_IC  NCSKEW-AbsACC insthold  DIRECTOR MAO,absorb(i.Indcd1 i.year) vce(cluster code)
est store m_1
qui reghdfe FNCSKEW  NCSKEW-AbsACC insthold  DIRECTOR MAO (CliqueOwnership=c.IC_Shock#c.Treatment_IC),absorb(i.Indcd1 i.year) vce(cluster code)
est store m_2
qui reghdfe FDUVOL  NCSKEW-AbsACC insthold  DIRECTOR MAO (CliqueOwnership=c.IC_Shock#c.Treatment_IC),absorb(i.Indcd1 i.year) vce(cluster code)
est store m_3
qui reghdfe FCRASH_COUNT  NCSKEW-AbsACC insthold  DIRECTOR MAO (CliqueOwnership=c.IC_Shock#c.Treatment_IC),absorb(i.Indcd1 i.year) vce(cluster code)
est store m_4

运行到qui reghdfe FNCSKEW  NCSKEW-AbsACC insthold  DIRECTOR MAO (CliqueOwnership=c.IC_Shock#c.Treatment_IC),absorb(i.Indcd1 i.year) vce(cluster code)
这句时就报错了parentheses unbalanced

检查了空格、括号的时候，找不出问题，各位大佬怎么办
