Visual Basic Excel Macro MessageBox.Show Throws "Object Required" Error - excel

Question

Simply put no matter how hard I try I cannot get a MessageBox to appear through my Excel macro.
Here is the line I have so far:
MyBox = MessageBox.Show("Stuff", "Title")
When I run this macro I get the following error:
Run-time error '424':
Object required
What's going on!?!?
Here is the complete code:

MessageBox.Show is VB.Net. Even though you have tagged it as VB.Net, I believe you are doing this in VBA.
Try this
MyBox = MsgBox("Stuff", vbInformation, "Title")
