Filtering to columns that contain a certain string, & only on and after a given date

Hi community,

I was given help months ago to come up with a script; it's been working wonderfully.  I now need to expand it.  This is how it looks currently:

CALCULATETABLE (

    ADDCOLUMNS (

        SUMMARIZE ( 'CM360', 'CM360'[Date], 'CM360'[Placement ID] ),

        "Cost-per-day",

            CALCULATE( SUM(('CM360'[impressions])) / 1000) * 4

    ),

    'CM360'[site_cm360] = "Programmatic Ads"   

)

---------------------------------------------------------------------------------------------------------------------------------

You can see we've created a calculated table where we've taken the [Date] and [Placement ID] columns from an existing table, 'CM360'.  We've then created another column, "Cost-per-day", calculated by taking [impressions], dividing that by 1000, then multiplying by 4 dollars. Only where the column, 'CM360'[site_cm360], contains "Programmatic Ads".

I would now like to expand that script to something like this:

    CALCULATETABLE (

    ADDCOLUMNS (

       FILTER ( 'CM360', (CONTAINSSTRING('CM360' ['Placement'], “banner”)), 'CM360'[Date] >= 01/09/2022 ),

        SUMMARIZE ( 'CM360', 'CM360'[Date], 'CM360'[Placement ID] ),

        "Cost-per-day",

            CALCULATE( SUM(('CM360'[impressions])) / 1000) * 5.00        

    ),

    'CM360'[site_cm360] = "Programmatic Ads" OR “iAgency”

)

I wish to filter what we were doing before to rows where 'CM360' ['Placement'] column contains the string "banner".

And only where those rows have the date on or after September 1st 2022.

Additionally, in that last line, I wish to expand it so it now looks for those two different values in the column,   'CM360'[site_cm360]

Please can you look at my expanded script and help me understand how you would write it because I don't think this is how it should be written in DAX.

thank-you  🙂
