Problem of Incompatable grids

[Hui Du]

Dear GrADs users:
I want to calculate the correlation between two variables which come
from two data sets. One is model output, the other is reanalysis data.
The domain of the model is a little bigger than the reanalysis, But part
of them are overlapped exactly. I have written the grid set at the last.
We can see that they are exactly the same except the blue part. My
script is

function wp ( args)
tb=subwrd(args,1)
te=subwrd(args,2)
'define avet2a=ave(t2.2,t='tb',t='te')'
'define avet20=ave(t2,t='tb',t='te')'
'define
cort2a=scorr(avet2a,avet20,lon=230.505,lon=252.651,lat=28.4976,lat=46.6943)'
'd cort2a'
return

When I ran the above script, I got:

ga-> run b.gs 613 736
Error from SCORR: Incompatable grids
Operation Error: Error from scorr function
Error ocurred at column 1
DEFINE error: Invalid expression.

I wonder where my problem was, when I calculate two model sets which
have the exactly same grid set. It was ok
Thanks lot
