on death platuge when you gotta buy harold the drink i have done it like 6 times and when i try to give him blurberry special he won't take it he keeps asking for asgarian ale. what do i do

i looked on runehq and the guide on here skips a step on death plague. you suppost to go back and talk to euchtor or whatever his name is after you talk to harold the first time

Um been a while since I did that one I beleive he only needed like 3 beers and you talk to him everytime, Im not sure? Also this should be in quest help sub-forum.
