Conditional compilation is turned off 

You attempted to use a conditional compilation variable without first turning conditional compilation on. Turning on conditional compilation tells the JScript compiler to interpret identifiers beginning with @ as conditional compilation variables. You do this by beginning your conditional code with the statement:

/*@cc_on @*/

To correct this error

• Add the following statement to the beginning of your conditional code:

  /*@cc_on @*/
