st: AW: Interaction with squared variable

This is the message I get when I use the command ( oprobit  y
i.gender c.x  c.x#c.x  i.gender#(c.x#c.x) )
"invalid interaction specification;
multiple 'o' operators attached to a single variable are not allowed
within an interaction specification{p_end}"

The same command works if I use a linear model that is regress y
i.gender c.x  c.x#c.x  i.gender#(c.x#c.x).

Thanks  in advance



" but it does not work".

What exactly does not work? Note the FAQ onthis point...
