Task validation rule

I have the following task validation rule to prevent a text box from being populated unless a specific picklist value is specified. However, even if the text box is blank, the validation rule still fires and displays the error. Help!


AND(
NOT(ISPICKVAL(Status,"Completed")),
NOT(ISNULL(Description)))

Hi Rung41,

You need to change your validation rule to 
  
AND( 
ISPICKVAL(Status,"Completed"), 
NOT(ISNULL( Description )))

I tired that. The user can fill in the text box even though the picklist is not set to Completed.

Ok..I had to change the "ISNULL" to "ISBLANK"
