and here's a good site on trancing a rabbit if you can't get her to stay still -

you might also want to try a "bunny burrito" tactic where you have the bunny wrapped in a towel and only pull out one foot at a time.
when I clip mine, I sit on the floor and flip the bunny over onto their back... I cradle the bunny in my left arm (I'm right-handed) and use my left hand to splay the paws/hold up a nail while using my right hand to clip.
if her nails are dark, you can have someone hold a flashlight behind them so you can see the quick... if there's fur in the way that makes it hard to trim her nails, do NOT cut/trim it as they need it to protect their paws because they don't have pads like cats and dogs do. instead, dampen the hair so it'll lie flat.
I like to keep a box of raisins or a plate with a few tiny pieces of fresh fruit beside me (raisins are easier for me because I have two bunnies and don't need the other one stealing treats, lol)... the bunny gets a raisin right after being picked up (before being flipped over) and once every 1-2 paws when I can tell they're getting fussy, I flip them over long enough for another raisin. they get one more when we're all done. it usually takes 4-5 raisins per bunny to bribe my way through nail clipping.
oh, and if you need to carry her to another room to trim nails and she struggles over that, I recommend ushering her into a travel carrier and using that to move her
