Hi BreakAway,
As MrP mentioned, the context will help to get the right answer.In general, following are the rules to use 'more than one':
(1) "more than one" + "singular noun" takes a singular verb.
(E-x) More than one customer gets discount.
(2) "more than one" + "of"+ "plural noun" takes a plural verb.
(E-x) More than one of the problems are resolved.
(3) more than one" + "<no subject>" mostly takes a singular verb.
(E-x) More than one has been enough for us to do it.
I hope this gives you some idea.
