how to refer to a toolbar item

Getting Started

I am new to Xojo, and I’m trying to figure out how to refer to an item on a toolbar. I have a webtoolbar called mainToolbar. On this is a webtoolbarcontainer called userContainer. Within that control I have a container called userNameContainer. Within userNameContainer is a weblink control called userNameLink. I want to set the userNameLink text property my Session.userName value. How do I refer to the userNameLink to set the value?

Thanks,
