Height of (iframe) mapbox

Hi,

I can not figure out why I can not set the height of my mapbox What I set.. it remains at about 150pixel…

This is the code I use in a text box:

<iframe src=”https://a.tiles.mapbox.com/v3/brabo.im05g2ne/attribution,zoompan,zoomwheel.html” height=”500px” width=”100%” frameborder=”0″> </ iframe>

The crazy thing is that it does look good in the editor. It seems like the iFrame can not set bigger.

Please help!
