Hi,

You can try this Validation Rule;

PRIORVALUE( ClsodeDate__c )  > NOW()

Hi, 

 

PRIORVALUE  return the last value that the field have defore modification.

 

So what I think you are doing is using PRIORVALUE  method in a Boolean Type condition. Look into it and if you are still getting an error, please supply the whole code for reference.

 

You can also use some thing  like this..

 

if( AND(PRIORVALUE( Email_Alert__c) > Email_Alert__c,ISCHANGED(Email_Alert__c)),true,false )
