Authorize.net (SIM) - transaction not showing up

This is my first shopping cart - I think I have set up Authorize.net (SIM) correct; zen-cart currently in test mode

I can see order transactions on zen-cart admin; but when I login to Authorize.net to check - I don't see any transaction.

Did I miss a step? Can someone help?

Thanks
Niki

When you're in test mode, you won't see the transactions in your authorize.net account.
