Google Help!

I have scanned these boards, tried multiple things with no success.

I have a google docs form that I would like to put on a page.

When I put the html code in, the form comes up as a blank image.
When I go to visual, I can see the outline of a box with the words iframe inside but no form.

Here is the form : https://docs.google.com/spreadsheet/embeddedform?formkey=dG4tQzFhTEFGSDBDRTVvMHpoZXYya1E6MA

I have tried the following unsuccessfully

<div style="text-align: center;">[googleapps=https://spreadsheets.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key= dG4tQzFhTEFGSDBDRTVvMHpoZXYya1E6MA;output=html&widget=true]</div>

<p><iframe frameborder="0" height="1503" marginheight="0" marginwidth="0" src="https://docs.google.com/spreadsheet/embeddedform?formkey=dG4tQzFhTEFGSDBDRTVvMHpoZXYya1E6MA" width="760">Loading...</iframe></p>

<iframe width=100% height=560px frameborder=0 src= https://docs.google.com/spreadsheet/embeddedform?formkey=dG4tQzFhTEFGSDBDRTVvMHpoZXYya1E6MA &embedded=true></iframe>

Any advice?
