Adding another condition to my sum if function

Hello,

Below is my function.

="Profit $"&SUM(IF(Sold!D15:D8998<>"",IF(MONTH(Sold!D15:D8998)=A4,Sold!H15:H8998)))

I would like to edit this function to also count profit only if Cell A15:A8998 in my Sold sheet has the words "Shipped". The text value Shipped is not a text value I entered, it is automatically written based on a Vlookup formula I created. Any help on how to get this working with my function above will be greatly appreciated.

Perhaps

="Profit $"&SUM(IF(Sold!D15:D8998<>"",IF(MONTH(Sold!D15:D8998)=A4,IF(Sold!A15:A8998="Shipped",Sold!H15:H8998))))
