VB.Net จะดึงค่าจาก Textbox ใน Form1 ไปที่ฟอร์ม Form2 แต่มีปัญหา Array

public tb(,) as integer

ReDim tb(CInt(tbxRow.Text), CInt(tbxColumn.Text))

        Dim k = 0
        For x = 1 To CInt(tbxRow.Text)
            Dim l = 0
            For y = 1 To CInt(tbxColumn.Text)

                tb(x, y) = New TextBox
                tb(x, y).Location = New Point(30 + l, 120 + 25 + k)
                tb(x, y).Size = New Size(50, 20)
                Me.Controls.Add(tb(x, y))

                l += 60
            Next
            k = 25 * x
        Next
        k = 0
        For x = 1 To CInt(tbxRow.Text)
            Dim l = 0
            For y = 1 To CInt(tbxColumn.Text)

                tb(x, y) = New TextBox
                tb(x, y).Location = New Point(30 + l, 120 + 25 + k)
                tb(x, y).Size = New Size(50, 20)
                Form2.Controls.Add(tb(x, y))
                l += 60

            Next
            k = 25 * x
