Using Elements In Second Queue Of Another Form After Transfer

I have a form that has a queue and I want to transfer the data of that queue to another queue in another form. however when i try to use the elements in the second queue after transfer, I get the error message queue empty!

Below is my code
First form
Imports System.Collections.Generic
Public Class Form1
Dim wait As New Queue(Of String)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code] .....

I expected the recieveQueue function to copy the queue passed to it into the waiting queue, then it allows me to use the waiting queue contents as I want. But when I try to use it, around this line I get the error, 'queue empty' < If waiting.Count > 0 And waiting.Peek <> "" Then >
