Find Revenue per Client for specific time period

[Anonymous]

Hello again friends!

I need help on something that is probably very easy that I am likely overthinking. I need to determine the revenue per client for their first 12 months after their go-live month (between 'Opportunities'[Start First 12 Months After Ramp] and 'Opportunities'[End of First 12 Months]). Related table 'Sales Data' contains a [Total Revenue] Measure. See below. I have tried dozens of different combinations of datesbetween and whatever else I could find, but I either receive an error or the new column shows ALL the revenue for the entire time period and does not filter by client Account Number. How do I solve for this?

*Note: the below screenshots only show what I thought is relevant to this question, there is a lot more that is hidden for confidentiality.

Thank you!

I realized I had a hiccup in one of my relationships that caused my measures to produce the same data down the whole table column: that is fixed, but the problem creating a measure to find the revenue for the timeperiod still stands. I receive errors that I dont know how to fix or the date is entirely off. Thanks!
