issues with abbr tag in php array. only shows until first space

i am trying to incorporate the abbr tag into my php array, so that when an
abbreviation for an airport, such as MSP or AMS shows up, when you hover
over it it will show the full name of the airport.
the code that I am using is:
echo " <td width='70' bgcolor='$row_color'><img
src='../flags/".$row['countryflag']."'>
&nbsp;&nbsp;<abbr
title=".$row['luchthavennaam'].">".$row['luchthavencode']."</abbr></td>";
It will show me up until the first space in the name of it and then cuts
it off. When i run my query in Toad, I do see the full name show up, so
it's something with how I'm working this.
any thoughts?
