title: Oracle: error while trying to use formulas
body: <p>I created an element with an input value of type "Day" , when i write a formula i get this error.</p>
  
  <p>Any idea what's wrong?</p>
  
  <blockquote>
    <p>APP-FF-33232:
    EATC_EXTRA_DAYS_ENTRY_EFFECTIVE_DATE_ENTRY_VALUE has null or not found allowed, but no
    default set specified.</p>
    
    <p>Cause:        If a Database Item has
    null allowed, or not found allowed,
    then the item must also specify a
    default set to be used to provide
    default values in the event of these
    occurring.  The item named has one of
    these conditions allowed, but the
    default set column in the
    FF_DATABASE_ITEMS table is null. </p>
    
    <p>Action:        Please refer to your
    local support representative.</p>
