Unapply a Credit Memo from an Invoice.

Please, help!

I applied a credit memo to an invoice in error. I want to remove that memo. I found on internet these steps:

1. Find and open the credit memo in your Quickbooks account.
2. Display the history associated with the credit memo by pressing Ctrl + H (shortcut command for history).
3. Double-click the invoice on which the credit was applied.
4. Click the Apply Credits button.
5. Clear the current credit selection in the Previously Applied Credits window.

(Title has been edited by moderator for clarity)

1. Click Done on the Apply Credits window.
2. Click Save & Close on the invoice to remove the credit and save your changes.

But, i cannot find the Apply Credits button. Where is located this button?

Thanks,
