regoprob shows factor variables and time-series operators not allowed r(101)

I am doing HGLM analysis with ordinal outcome, data are from 19 countries and the dependent variable is Job Security. and the syntax is:
regoprob JobSecurity i.Female##c.WelfareIndex i.Age_gru SECONDARY Partnered Children PARTTIME UNIONM CIVIL JobintFam FamintJob GDPPerCapita,
i(COUNTRY) npl(CIVIL JobintFam GDPPerCapita)

but it shows
"factor variables and time-series operators not allowed
r(101);"

How can I fix this problem? If anyone can provide some suggestions I will really appreciate it.
