Hi there. I had the same problem with Nutramigen (a different elemental formula). Elemental formuals taste horrible! I found that if I warmed the bottle, I had more success. My son eventually got used to it, and he adjusted. But it took some time. She will take it eventually. Try warming it up. Also, if she isn't allergic to soy formula, adding a scoop of that in also helps. I tried both of those things and eventually had success. She will adjust, it just takes time. Good luck!
