Launch Flash. There should be a blank canvas already shown. Go to Modify, Movie and make the movie dimensions 400(width) by 275 pixels. Select the Text tool and using a large typeface, type "form" at the top left hand side of the canvas. I used Helvetica Neue in bold as the font. Name the layer that you're working in "Header" and lock the layer. Locking the layer ensures that you will not accidentally edit anything in that layer.
