GRT Avionics

I created the .txt doc for the userdb airports using the example in the miscellaneous files so I could shoot synthetic to my grass field. Neither my HXrs nor my Mini-X will load the .txt. They all say "unloadable". Load user database option is set to "yes". Below is my file, which is saved as a .txt. I have this file called userdb-my airports.txt, but no matter what i call it .txt, it wont load. What am I doing wrong?

<GRTUserDB>
<Airport ident="7MD1">
<Runway surface="GRS" length="2500" width="50" >
<RunwayEnd ident="09" lat="38.703102" lon="-75.854950" elevation="50.0" dispthr="100" />
<RunwayEnd ident="27" lat="38.704693" lon="-75.846039" elevation="40.0" dispthr=25" />
</Runway>
</Airport>
</GRTUserDB>

Thanks for any help!

You are missing the opening quote around 25 for the dispthr value in the RunwayEnd line for runway 27.

Oh good god. How stupid. Thanks Jeff.
