point query for multiple layers {Scanned}

[Brent Pedersen]

yes, see the layer defs below in my original mail.
i've tried both with a different template for each layer and the same  
template for all 3 layers. neither works.
my query string looks like:
?mode=query&map=...&layers=FRAP+WUI&imgext=....&imgxy=...&imgsize=520 
+600
i know the imgext and imgxy are correct because it does return the  
correct value for the layer that is does query, but just nothing  
happens for the other layers. i also did try this with mode=nquery.
