ok i found this on one of the othe forums for you ilia and i believe its what you need.if im not mistaken you want it to stop after X number of questions BUT not reset the scores.so this is what i found.
in the automation tab of the settings set it to reset after <the number you want> questions, then in the code under the reset Trivia section disable the following lines
mstat *s4 $stm(reset)
.timerst_resetscores 1 10 st resetscores
.timerst_restart 1 10 st start
to be honest i dont know how to disable this line .my guess(and this is just a guess,as i havent tested this)is to add ; before mstat.i have a cpl bots i dont use too much so i wil load trivia in them and try it and let you know what happens.and so you all know that code is firehouse's code.
