Here's some more information that may help you, but don't give up: Select the AutoShape (AutoShapes: A group of ready-made shapes that includes basic shapes, such as rectangles and circles, plus a variety of lines and connectors, block arrows, flowchart symbols, stars and banners, and callouts.) or text box (text box: A movable, resizable container for text or graphics. Use text boxes to position several blocks of text on a page or to give text a different orientation from other text in the document.) that contains the text you want to wrap.
Double-click the selection rectangle (selection rectangle: A rectangle with sizing handles that surrounds a selected object or objects.) of the AutoShape or text box, and then click the Text Box tab. Select the Word wrap text in AutoShape check box. Also, don't you have a "help" feature in your PowerPoint software?
