"Wron Expresssion" error on nested query

[Frank Bitterlich]

Hi,
I get a 616 error ("Wrong Expression") on the following query:

select * from NAVAIDS where (((LAT1<=28.60547) and (LAT1>=27.63281)) 
and ((LON1>=-80.01172) and (LON1<=-78.43359))) or (((LAT2<=28.60547) 
and (LAT2>=27.63281)) and ((LON2>=-80.01172) and (LON2<=-78.43359)))

All fields (LAT1, LON1, LAT2, LON2) are VDouble.

What can be the reason? Is the query too long, or too deeply nested? I 
have counted the parentheses, they appear to match. Or is there any 
stupid mistake that I'm overlooking?

V4RB 1.11, RB 5.5.4, OS X 10.3.5

Thanks,
    Frank+++
