APEX

Good Afternoon,

I am using APEX 5.1 Oracle DB 12c and Google Chrome

I have a question in regards to the Logic behind Server Side Condition on a Button

The Button's Behavior is to Redirect to Page in this Application, but if an Item doesn't exist I want to Hide the Button.

If I choose Server - Side Condition: Item is NOT NULL , Item: P64_RECEIPT_NBR

Then the Button Hides (which is What I Want)

, but if I choose Server - Side Condition: Item Is NULL then the Button Appears on Page

This seems to be Reverse Logic or I'm just Logically thinking about it in the wrong manner

--------------------------------------------------------------------------------------------------------------------------------------------------

Here is the Item "Receipt" When NULL going to Redirected Page I want to Not Show "Refund" Button;

which Does work with: Server - Side Condition: Item is NOT NULL , Item: P64_RECEIPT_NBR

but opposite if there is a Receipt

Thanks and Best Regards,
