Please help. I dont know which account to credit.

A stock donation was received for $6000 at a Gala event and the Accounts Receivable staff credited the Gala Revenue account $6000 and debited the checking account $6000.

I now need to recognize the donation in our investment GL account. I know I need to debit the investment account but unsure which account I need to credit. I would think I would credit either the cash or gala revenue account but I'm unsure becuase I've never dealt with sock donaitons.

bi ABC Company received a $6,000 stock donation as a pledge at ABC's Gala Event. The accounts receivable staff has already made the following entry to receive the donation: Checking Account $6,000 Debit Gala Revenue Account $6,000 Credit You must now record make an entry to recognize this donation in your investment account. What will your entry be? believe I should debit the investment account $6,000. But I'm unsure what account I need to credit. Please help./
