It would help if you told us what the errors are.

EDIT:

I found it. Your "Merge" function doesn't have a body.

Specifically, your prototype is named "Merge" (capital M), but your function body is named "merge" (lowercase m), so the compiler sees these as two different functions. Therefore when you call "Merge", it can't find the body for it.

thanx a lot, for such a quick response. i am highly impressed. :):):)
mind gets so tired sometimes that it fails to catch upon slightest of most foolish mistakes..
