Visual Basic Member Already Exists in an object module

Question

I am brand new to visual basic today and I was writing my program but I get a compile error

Member already exists in an object module from which this object module derives

My function prototype is

Function calculate(count As Integer) As String

I was wondering why this is giving me this error

Answer 1

It would appear that you are designing a form, and have an object on that form (such as a text box or command button) which is also named calculate, disregarding case, since VBA is generally not case sensitive.
