In need to do same as following:

if ( SpeakerID == "ronda nyme" )
"ronda ynime"-> removeitem "myr_snakejewel_g_sh" 1
elseif ( SpeakerID == "renata saas" )
"renata saas"-> removeitem "ko_black_sheith" 1
endif

Best Regards.

can't you just make the same dialog twice with one time the first speaker ID and the corresponding result, and the second time the other ones.

you can't do if statements in the results box.

You can. I did, several times. It works. Separate NPCs, though, are indeed much easier to handle through separate lines.
