error in the commentary section of NUX

Hi Community,

I got this error on the NUX from the client side and it is not quite clear what is the meaning of this message. I hope you can provide some insights on the matter.

Under Incremental NOI with the line item L2 Final Commentary the user is doing a copy and paste a comment drafted in PPT and then pasting it in the line item above.

In the source module L2 Final Commentary(text format) has a formula as below:

IF

    ISNOTBLANK(Commentary) AND ITEM('LIS009 REP003 SBU NOI') = 'LIS009 REP003 SBU NOI'.Store GP impact due to change in Sales AND 'SYS003.1: L4 SBU Mapping'.EMEAA Countries?

THEN

    Commentary & " by " & 'Round(Text)' & "m" & " - Due to " & NAME(ITEM('LIS009 REP003 SBU NOI')) & ". " & 'L2 Additional Commentary (Staging)'

ELSE

    IF

        ISNOTBLANK(Commentary) AND ITEM('LIS009 REP003 SBU NOI') = 'LIS009 REP003 SBU NOI'.Store GP impact due to change in Sales AND NOT 'SYS003.1: L4 SBU Mapping'.EMEAA Countries?

    THEN

        Commentary & " by " & 'Round(Text)' & "m" & " - Due to " & NAME(ITEM('LIS009 REP003 SBU NOI')) & ". RB Growth of " & 'RB Growth % (text)' & ". " & 'L2 Additional Commentary (Staging)'

    ELSE

        IF

            ISNOTBLANK(Commentary)

        THEN

            Commentary & " by " & 'Round(Text)' & "m" & " -  Due to " & NAME(ITEM('LIS009 REP003 SBU NOI')) & ". " & 'L2 Additional Commentary (Staging)'

        ELSE

         BLANK

Is the user not satisfying the condition on the formula that is why the error above is showing up.

Any feedback is greatly appreciated.

Regards,
