Thanks it gave me more to experiment with but even then I still can’t seem to get it right I have this if anyone knows why..
array(
'key' => 'sale_price',
'value' => 300000,
'type' => 'NUMERIC',
'compare' => '<'
),
array(
'key' => 'status',
'value' => '',
'compare' => 'EXISTS'
)
So I am saying nothing exists sort of thing..TY
