Date Validator

[Jacob francois]

I want to create a date validator. The below code works 

issue.get("Priority date for contract execution")>= new Date() + 14

but the problem is I'm using script runner to hide the above field based on answers the user selects. 

if (issue.get("Does this contract need to be reviewed and approved by legal?") == "Yes")
{
  
  issue.get("Priority date for contract execution")>= new Date() + 14
}

so I created the above if statement to test the value of a question. 

Is there something wrong with my code or there is way to create this same date validator with script runner.

To get value from transition screen you should use 

issue.?get("Does this contract need to be reviewed and approved by legal?") == "Yes"

 I get a error when trying to put the "?"
