Question about making fudge Help?

Ok so I want to make fudge so I will have it tomorrow. I have already been to the store and I do not wish to return again tonight. So I have all my ingredients but it calls for ¾ cup of butter and all I have is sweet cream no salt butter. Is that okay to use for fudge. I need help I really have a craving for fudge so I will greatly appreciate some advice. Thanks!
