WHERE - problem [message #33783]

hi there
i'm not an IDL-guru, but i'm using it for some time. the WHERE function
is extremely handy and often of great use for me.
however, one problem i failed to solve.
lets state an array(500,500,10)
array=INDGEN(500,500,10)

so then, the find=WHERE(array[*,*,1] GT 252000) returns me all the
needed values.
but HOW do interact with these.

a=mean(array[find]) doesnt do it right

So I helped myself with
idiotway=array[*,*,1]
find=where(idiotway gt 252000)
so then the example a=mean(idiotway(find)) does it right.

However, somehow there must be a better way...

some help would be appreciated
