Operator <> or NOT In. In and Exactin work but I would like the opposite

[Rebeccak]

I have 2 gallerys. The first Gallery is filtered by selected date. I would like to filter the 2nd gallery by a field not equal to a field in the filtered 1st gallery. 

Gallery 1 items=Filter(colFilterGallery1, Start>=StartDateSearch.SelectedDate&&end<=EndDateSearch.SelectedDate)

Field in colFilterGallery to compare "TechnicianText"

Gallery 2 = colGallery2

Field in colGallery2 to compare "ADTxt"

Im am trying to filter colGallery2 items. This is what I have:

Filter(colGallery2,Department = "On Call" && ADTxt exactin Filter(colFilterGallery1,start >=StartDateSearch.SelectedDate && End <= EndDateSearch.SelectedDate).TechnicianText)

This shows the match and is filtered correctly by date. But I would like it to show the opposite. Provide the "ADTxt" items that do not match the TechnicianText but are within the date range. 

Any help would be appreciated

I'm a little confused by what you're doing - is 'colFilterGallery1' a datasource?

Could you do a Collect() of the TechnicianText, and then in the filter of your second gallery set it to filter to items IN your collection, but wrap that inside a Not()?

Yes, I am sorry. It's 2 different data sources. I just want to compare a field in each datasource to filter by.

I figured it out. I used my original filter and wrapped it in a Not()  Thanks

Hi @Rebeccak,

Have you solved your problem?

If you want to filter your Gallery 2 whose ADTxt" items that do not match the TechnicianText but are within the date range, please modify your formula as below:

Filter(
     colGallery2,
     Department = "On Call" && 
     Not(ADTxt exactin Filter(colFilterGallery1,start >=StartDateSearch.SelectedDate && End <= EndDateSearch.SelectedDate).TechnicianText)
)

More details about the Not function, please check the following article:
