'End Class' must be preceded by a matching 'Class'
End Class is used to complete a Class block; hence it can only appear at the end of the block. Either you have a redundant End Class, or your End Class statement appears outside the bounds of its corresponding Class block.
Error ID: BC30460
To correct this error
Locate and remove any redundant End Class statements.
Move the End Class statement to the appropriate location in your code.
