if controller problem

[James Bull]

I am getting the error

2007/04/04 18:34:35 ERROR - jmeter.control.IfController: "Default" is not 
defined. ReferenceError: "Default" is not defined. (<cmd>; line 1)
        at 
org.mozilla.javascript.NativeGlobal.constructError(NativeGlobal.java:597)

I am using a regular expression extractor on the previous page to set a 
variable with a value.

Then in the if controller I am using the expression

${calendarPresent} == "There is no calendar"

What am I doing wrong?

Thanks,

James
