[rules-users] Variable Notation in rule Condition

[sumatheja]

Hi All,
        I have this doubt regarding the notation used inside the rule's
condition. I have a fact HOST having the variables* HostName* and *
CPUSockets*. I have the following rule

rule "Test"
when
HOST(HostName!=null, CPUSockets>3)
then
# do something

Is throws an error saying cannot extract field *HostName*. It works fine
when i use *hostName*. Can anyone explain me the concept behind this.
Thanks in advance :)
