Adding confidence intervals in two-way graph using logit regression

[chels johnson]

Hello, I am attempting to add confidence intervals to a two-way graph involving three separate regression lines, but I'm getting an error message (r198, option ci not allowed). I've copied my stata script below for reference. Any advice on where I'm going wrong would be very much appreciated.

Thanks in advance!
