c still equals 1. If you want to change c to be 17 in the function, pass it ByRef, or make the CheckValue a function with a return type. Based off your post, you want to do this:

Sub CheckValue(ByRef iValue as Integer)

Passing ByRef passes the object, passing ByVal passes the Value of the object.

yeah tibby is right...even c assign a value of 1. When you pass to the Sub CheckValue(ByVal iValue As Integer)... the iValue now is 1 which you pass, but in the method, you assign iValue which is equal to 13, you have a new value stored in iValue, so after the execution, still c is equal to 1 and your iValue is 13...
unless you make a function which return a value that makes c change...
