nargin is useful inside functions (m-files of which the first non-comment is the word function). Since you say this line is the first line, I suppose you're dealing with a script, for which nargin returns 0, hence the error.
I do not know what you mean by "5 inputs in the worksheet". Do you want to say you have 5 variables in your workspace? And that these 5 variables are the be used by the m-file?
