Re: The set does not exist

Carl,

Hi. Couple of obvious things to check:
* have you used the correct name in the $ListBoxName variable?
* what does $tableNum contain? It should be a valid table number

Regards,

Subject: The set does not exist

    Using the following method, I get the error "The set does not exist".
    
    $ListBoxName:="ListBoxObjectName"
    
    LISTBOX GET TABLE
    SOURCE(*;$ListBoxName;$tableNum;$namedSelection;$highlightSet)
    
    USE SET($highlightSet)
    
    I select records (rows) from the listbox before running the method.
    
    I obviously have a lack of knowledge. Can anyone guide me in the right
    direction? Can't find anything in 4D Knowledge Base.
    
    Regards
    
    Carl
