Using AP 2.0 within Dreamweaver

While in dreamweaver mx, and adding the ap snippet within a layer it displays correctly and operates correctly. After working with the page for a while, all of a sudden my design layout dissappears and all i have left is a little php icon........I have tried this three times and the same results...is it that the code is not compatible with DWMX......thanks in advance for any help......

the best way is to edit your page with a simple text editor like homesite

In dreamweaver, when you add tags incorrectly, it will not be able to display correctly. To preview your work, press the F12 key. To correct your mistake press Ctrl-Z till the part where the mistake occurs.
Good luck!
PS: I am also using dreamweaver with the Poll and have no problem incorporating it.
