Hi. I have a login webpage and a welcome webpage. I have the usernames and passwords saved in a database. After login I redirect to the welcome page. Let's say I login as Dave. I want the welcome page to say Welcome Dave. 
How do I do this?

I tried a bunch of things unsuccessfully - I created a label on the welcome page and tried calling it from the login page but that wasn't allowed. Is there a way I can connect labels from different web pages??
Are there tools in the toolbox that can link pages together?

Or should I focus on doing something with the database?

Any ideas?
