Access Message Box using dlookup

Hate to seem like I'm slacking on reasching end, but I'm looking for a function what would display a tabel value using a message box. I have a table called, tlbVerisonServer and with column called "VersionNumber" (numeric value).

I just want a fucntion that would procdure a message that says, "Current database version is "Version Number" (the actually table value"). I really don't hate to ask someone to do all the work, but I'm curious to see how setup would be. I want to do some things in my database for learning and testing purposes.

Thanks
