If you haven't already, you need to learn to read Alamy's rather obfuscating sales reports so you know where things stand. The only thing that's right up front on the dashboard is your current cleared balance - which may be $0 even if you've made sales and the gross value of sales you made in the current month.
If you click on the Sales History button, that will show you gross sales and any refunds. This money is not what you will earn - you need to see the net amount and what has cleared by clicking the Account Balance button.
For every sale, you can see the details on what your royalty is - at least, if you subtract any distributor's take and Alamy's take from the gross sale, you can see what your net amount is. On the far right is a column that shows o for cleared, x for uncleared and a date if they've paid you already.
