Function Call Errors

[Michael Kay]

You've declared a function that expects four parameters and you've called it
supplying only one.

Since sorted_result, count, and doc are the names of local variables within
the function I suspect you should just omit these parameter declarations.

Also you refer to a variable/parameter called $ad but there isn't one. I
suspect you meant $seq.
