Question : Google maps map not centered

I have a website in which i have to dynamically show the map of a certain address. I currently use the enclosed html-code:
The problem is that the marker is always outside the window. I need to have just a marker (without the actual address etc) of the address, and this addres must be centered on the map. The address is dynamically, so i can't use lat/lang coordinates.
