Having problems with TabControls

I am trying to change a tabpage name on a parent form to what a user types in a textbox on a child form when a strip menu button is clicked. I have everything working in that I can pull the correct information between both forms but every time it goes to get the currently selected tabpage it always returns "0".

Function to set new tabpage name on Forum1 (The message boxes are from trying to debug)

public void setNewTabName(string TextBoxText)
    {
        MessageBox.Show("Called");
        MessageBox.Show(TextBoxText);
        int CurrentSelectedTab = tabControl1.SelectedIndex;
        MessageBox.Show(CurrentSelectedTab.ToString());
        tabControl1.TabPages[CurrentSelectedTab].Text = TextBoxText;
    }

Function (Form2) for getting the textbox info and passing it to Form1

    private void button1_Click(object sender, EventArgs e)
     {
         BT frm1 = new BT();
         frm1.setNewTabName(getTextBoxInfo());
     }

    public string getTextBoxInfo()
     {
         return textBox1.Text;
     }

Any help would be greatly appreciated. I think I posted all the relevant code but if you need anything else I can post the whole thing. The only thing that is really left out is that it creates a new tabpage on a button click.

Edit: The same method works fine when it is taken out of the child GUI.

I think that the problem is that you create a new form (class BT) each time the button is clicked. I suggest you to move the form creation from button click event to parent form load function.
