Multiple constraints expression for a field?

[BryceHancock]

Hi, I have an integer field where I have added the following expression to the constraint field:

.>0 and .<360 or .-99

I want the user to be constrained to enter numbers between 0 and 360, or allow a -99 to be entered. Can this be done with a constraint field? If so, what is the proper expression?

(.>0 and .<360) or .=-99

Thank you, it appears

.>0 and .<360 or -99

, works as well.
