Anyone have a clue as to why this is happening?

I have a field gmap  the data would be  a variation of this, the gmap data to place the map on the site. The rest of the string is in my code because I want to size the iframe etc. Whean I use an input form to update this field using Null data and using a simple text line like yellow, the script works, when I try and add data as below I get a 403 error, how can I resolve this?
