I have a pot of flowering tulips, leaves are folding/curling & tips are turning brown.....what's wrong?

I was recently given a pot of flowering tulips (about a week ago). The flowers have wilted and I've snipped the stems off low near the leaves...soil has been kept moderately moist and pot is in high - but not direct - light area away from drafts. Recently the leaves have begun to fold/curl inward and the tips are brown but not crisp......I'm wondering if it's a watering issue or perhaps location (do they need to be outside?)......any info would be greatly appreciated. thanks!
