[antlr-interest] "No viable alternative" error

I've attached my grammer file. I'm getting the "no viable alternative"
error when parsing.
This statement works.
"select * where a < 5"
This one fails
"select * where a lt 5"
I'm a bit lost as to why, my rule for expression is defined in this way.
//mathmatical equality operations
property LT<LessThan>^ value
|property LTE<LessThanEqual>^ value
|property EQ<Equal>^ value
|property GT<GreaterThan>^ value
|property GTE<GreaterThanEqual>^ value
Then LT is this in my tokens
LT : '<' | 'lt';
Any help would be greatly appreciated! All my operations for equality ops
do it, so I know I've defined something incorrectly in my grammer.
