InfoPath Dev

I have a section that i would like to hide

I check the box to hide it then create my condition rule,

my condition is: Arrival City Does not contain ", USA" 

 my understanding is that if this condition is true, it will keep the section hidden

if i choose a record that contains "USA" it should appear, but it doesn't. 

Cant figure this out.... let me know if you need additional information

let me know if you need additional information

 not sure if this matters, but this is an example string i am working with

Monterey, CA, USA  - MRY
