Formula won't work on blank cell

[Kmurray]

Sometimes in my formula-a cell has no amount for that day, but I still have to put in a 0 in order for the formula to work. Is there something I can do so I don't need to enter zero's all the time?

1) Please post your formula so we'll see what you're working with.

2) Also change the title of your post (perhaps to what I used), so readers will have a better idea of what your question pertains to.
