Sumif between 2 numbers

Hi All

I am trying to create a measure that shows me overdue invoices between 0-30 day, 31-60 etc. I can not create calculated columns (which I am used to), so having to create measures. I have a measure for the days overdue:

Days = SUMX(INVOICES,DATEDIFF(INVOICES[INVOICE_DUE_DATE],TODAY(),DAY))

I now want to create a card that shows that total owing for 0-30 days.

I have managed to create a measure for a specific day overdue., in this case 9 days, but how can I do between 0-30 days?

0-30 = SUMX(FILTER(INVOICES,INVOICES[Days]=9),INVOICES[REM_BALANCE])

I have exhausted google!

Thanks
