    Hi FP68 

    here the correct code

     

    ApplicationName =
    VAR TagText = Disques_Global[TAGS]
    VAR _Key = "ApplicationName="
    VAR KeyPos = SEARCH ( _Key, TagText, 1, 0 )
    VAR ValueStart = KeyPos + LEN ( Key )
    VAR SemiPos = SEARCH ( ";", TagText, ValueStart, 0 )
    RETURN
    IF (
        KeyPos = 0,
        BLANK(),
        IF (
            SemiPos = 0,
            MID ( TagText, ValueStart, LEN ( TagText ) - ValueStart + 1 ),
            MID ( TagText, ValueStart, SemiPos - ValueStart )
        )
    )
