Missing Particle Size and Random Size on Physics 2.79b

Hi, I’m taking a tutorial on particles and came to a spot where i couldn’t do what he was doing because something was missing.

I’m unable to find particle size and random size anywhere.

I googled the problem and found one page where someone said that there was an advanced button somewhere which made it available but I also couldn’t find the advanced button so here I am…

Thanks for any assistance.


hey moderator, sorry about the second post on this, i didnt realize the forum was moderator reviewed at first and thought my post just vanished.
