I have created an IIf statement that i dont want to show up in the query result, so i have unticked the "show" option as again i dont want it showing up on the result once the query is ran. But every time i untick it then save the query the expression is being deleted automatically, but when i leave it as showing up in the query result it saves fine and does not delete it as it would when it is unticked. Anyone with a solution to this funny?
