"Access this application" window is blank

"Access this application" window is blank

I am a first time user of creator.  I have created a simple app named app1 with a form called form1 to test with.  I added a single line object called field1 and hit "access this application". The resulting page is a completely blank white web page. What am I missing? It seems odd to me that I can't find whatever options are needed to show the form. Perhaps I am missing some fundamental concept....
