Class toggle with repeat element

Hello .

I am trying to change the css of the column with the dynamic value is different:

dmx-class:sendermessage="(serverconnect2.data.queryUser[0].ID_user == serverconnect4.data.repeat1[0].query1[0].SenderID)"

I have been trying for days it is not working. When I write the name of the class to the container. It is working but when I use the class toggle and condition it is not working. I don’t know what exactly I am missing here.

Thank you for your help.
