Filter Custom Visual, Scroller, by a slicer

Hi,

any help with this dax issue I am stucked on, is immensely appreciated.

So, I have added a scroller custom visual to my dashboard and date slicer doesn't seem to affect it. There are various comments for each date. Even when slicer is applied it just keeps showing all the comments.

Is there anyway to filter with dax, so this scroller ticker shows only comments corresponding to the selected date?

Here's the relationship between table containing comments and date table. Fecha(AnomaliasKW) has a N:1 relationship with Date(Calendario)

I have tried something quite simple, filtering the AnomaliasKW table by the value selected in the top slicer but there I got another error that the expression is referencing to various columns.

Thanks
