[Mapserver-users] mapscript - queryByPoint help, simple Q

Thanks, I changed this and no change to the outcome.

However, I added the TEMPLATE tag to all of the layers and then suddenly, 
on the last layer:

Warning: MapServer Error in msOpenSHPFile(): No (NULL) filename provided

This is using $mapObj->query...

With the $uLayer->query it just says no records.

Then when I changed $uLayer to the last one they both give the NULL error.

I'll go bald with all this hair pulling out!

Thanks,
