ASP.NET Form HELP

[the_future21]

I am creating a print page for my form and when the print button is hit it sends the information in the textboxes, and checkboxes to a plain page and and I have labels set up to display the information.

I have an area were they check if they need an update done, something new added, or something deleted. On the page I only want one to show up on i.e. if the checked add I just want the label to say Add Requested.

the error i am running into is it is saying"
Var. 'Add' is used before it has been assigned a value. A null reference execption could result at run time.

It says the same thing for change and delete. Could someone please help w/ this problem.

Dim Add As CheckBox
Dim Change As CheckBox
Dim Delete As CheckBox

        If Add.Checked = True Then
            Add = Page.PreviousPage.FindControl("Add")
            lblAdd.Text = "Add Requested"
        ElseIf Change.Checked = True Then
            Add = Page.PreviousPage.FindControl("Change")
            lblChange.Text = "Change Requested"
        ElseIf Delete.Checked = True Then
            Add = Page.PreviousPage.FindControl("Delete")
            lblDelete.Text = "Delete Requested"
        End If

Before you can check wether the checkboxes Add, Change and Delete have been checked you have to assign them to the PreviousPage.FindControl

Dim Add As CheckBox
Dim Change As CheckBox
Dim Delete As CheckBox

Add = Page.PreviousPage.FindControl("Add")
Change = Page.PreviousPage.FindControl("Change")
Delete = Page.PreviousPage.FindControl("Delete")
If Add.Checked = True Then
     lblAdd.Text = "Add Requested"
ElseIf Change.Checked = True Then
     lblChange.Text = "Change Requested"
ElseIf Delete.Checked = True Then
     lblDelete.Text = "Delete Requested"
End If
