OR in slices

[fr_nick]

In DATA > Slices

I want to have a slice that refrences a col that has a dropdown 

The dropdown has 6 options.

I want the slice to show content from two of the six options

I've tried different OR formulas but nothing is working, thank you. 

For example  this works: 

Row filter condition  [STATUS] = "Delivered"

I want this to work :

Row filter condition  [STATUS] = "Delivered", "Ready to Deliver"

Thank you
