Too long countifs statement

Hello all,

I have a problem with my countifs statement in that it is too long. All that I want to do is count how many rows do not have an NA value. The problem is that I want to do this with multiple columns. Attached is a sample of what I am talking about with my countifs statement. I think a sumproduct formula would work here, but I can't seem to figure it out. Any help would be greatly appreciated. Thanks.
