coordinate use problem

Hi

I use function "wgt_areaave( VAR( {-10¡G10},{-20¡G200} ) , 1 ,1 ,0 )" to calculate the area average
(The area range which i need was latitude ¡G -10~10 longitude ¡G -20~200 )¡A
But the coordinate variable of VAR is ¡G
Variable ¡GVAR
Dimension and sizes¡G [ lat | 73 ] x [ lon | 144 ]
Coordinates¡G
                      lat ¡G[ -90...90 ]
                      lon¡G[ 0....357.5 ]

When i use "wgt_areaave( VAR( {-10¡G10},{-20¡G200} ) , 1 ,1 ,0 )" ¡Ait seems only
use the range (latitude ¡G -10~10 and longitude ¡G 0~200) to calculate the area average .
The area of (longitude ¡G -20~0) was been ignored .

How could i do ?

Thanks
