SUMIF with Stratification help

Hello All,
Hope everyone is well.
I need some help creating a formula that will count/ sum values based off a defined stratification bucket. On the Summary Tab, you will see I need to calculate in B3 the number of "indirect" (this comes from the "Data" tab - column "F") transactions that had an invoice price (from the Data tab) less than $0 and then $0-$5,000, and finally invoice price $5,001-$25,000. Next, instead of counting the transactions, I need to calculate the trade-in value (sum) for these stratification buckets as well. The Trade-in value is the Data tab, column "I".

Is there a way to write a sumif / counting formula to solve my problem?

Any and all help is much appreciated!
