It can't be "fixed". There is no such option over() to use even once, and still less repeatedly. As is implicit in the help and explicit in the code tabplot is a wrapper for twoway, principally twoway rbar, and not at all for graph bar or graph hbar, as would be needed for that syntax to apply.

Your intent is hard to decode but you want to plot six variables at once, which is two more than tabplot can handle.
