The comparison operation specified by expression "%1" is invalid.  
To use comparison operations, specify "$(op)(value)", where (value) is the value to match, and (op) can be one of the following operations:
Numeric: >,>=,<,<= 
String: <>
String wildcard matching: $=(pattern)
(pattern) may contain "*", which matches zero or more characters. For example, "$>10" means greater than 10, and "$=c*t" matches strings including 
"cat", "cart", etc. 
Use "$$" to specify the "$" character at the beginning of the value.
