Adobe Photoshop CS3: text becomes marquee after commit current edits

Adobe Photoshop CS3: When type text, it becomes marquee after commit current edits
I am creating an invitation using Adobe Photoshop CS3 then when I create a text in front of the image, I can type characters but nothing appeared Text Layer on the layers tool and after committing changes or edit the text becomes marquee and leaves the image of the text on the image.
What was happening?
Help me please! I am stocked with this.
