great, i see what you're talking about now. if you are having trouble with the ryhthmic aspect of it,try simplifying it at first and just think in eighth notes. (1-and-2-and-3-and-4-and). the litle embellishments in that are easy once you get that. if you're having a trouble with fingering it fast enough, i'll check these measures out at home today and see what i encounter. those vertical lines at the top of the tab notation (next to the 1st string) are the beats, so that gives you an idea with where the upbeat and downbeat will be. i think once you get that, the little 16th note ideas won't be too much of a problem.

i'll reply back to this once i check it out for myself.
