    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 )
        )
    )
     

    If this helped, please consider giving kudos and mark as a solution

Please try the following formula:

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 )
    )
)
