在利用协方差分析数据时，显示以下错误，小白初来乍到还在看教程不晓得该怎么处理，于是前来求助。如下图

命令为：anova wage children married children* married education,continuous(education)

按说应该是没问题的，我是对着教程的视频输入的，然后结果输出是这样：
option continuous(education) not allowed
    Option continuous(education) only allowed under version control with version
    < 11.  Or, use the c. factor variable operator on your continuous variables.
r(198);


希望有经历过的前辈指点一二。
