Message Template Condition

Since the message template "if" logic does not support "else", how to write "does not contain"? I tried both methods below when testing the template but they do not display their results.

%if (!(%Shipment.TrackingNumber%).Contains("1Z"))
USPS
endif%

Or

%if ((%Shipment.TrackingNumber%).Contains("1Z")==false)
USPS
endif%

Try putting spaces around your operators.

Nope. Does not work either.

I even tried all of this. OP says it worked when processing live and not from testing template. Could this be the case? Or is this a syntax problem. I have the opposite issue as this thread. Even using simple "contains" fails when in production but passes when tested. Very inconsistent behavior.

It worked for me in both "live" (Add shipment to order / enter tracking number / selected "Shipped"), and with the "Test template" on the Edit page.  
(using 4.60.4 on my dev PC)

%if ((%Shipment.TrackingNumber%).Contains("1Z") == false)
USPS
endif%

%if ((%Shipment.TrackingNumber%).Contains("1Z") == true)
UPS
endif%
