I can see the fields on the page you posted the link to, but I'm not sure exactly what the problem you are experiencing is. If you would like to make the text field on this page a select list then you can do so from withing DW. You can make a new select list and then just name it the same as your text field, then you can remove the text field.
If you are trying to do something else with the page or have a different problem please post back and let us know with a little more detail about what you are trying to accomplish and what you have done to get the current result.
