有完整的代码吗？以及报错结果？

求助！我也遇到了这样的问题，这是我的代码：
bootstrap direct=r(direct) ///
          indirect_INF_GII_RES =(r(INF_GII)*r(GII_RES)) ///
                  indirect_INF_DX_RES =(r(INF_DX)*r(DX_RES)) ///
                  indirect_INF_GII_DX_RES =(r(INF_GII)*r(GII_DX)*r(DX_RES)) ///
                  indirect =(r(INF_GII)*r(GII_RES)+r(INF_DX)*r(DX_RES)+(r(INF_GII)*r(GII_DX)*r(DX_RES)) ///
                  ,reps(500) nodots:bootm1

结果：direct=r(direct) command not found
