St Focus on a TextBox

Hello,
I am trying to run a command which would set focus on a TextBox called "SummaryFilter" so I could type into the box immediately without manually selecting / clicking into it.

This is what I am trying to do:

Please Login or Register  to view this content.

but it returns an error.

Could you please advise?

Thanks

I added the textbox to the worksheet through Excel's Menu bar by clicking:
Insert/ActiveX Controls/Text Box

FYI
Thanks

Thank you sintek, it works!

Not very elegant, but this worked for me. Instead of using TextBox1.SetFocus, I called this sub:

Private Sub resetfocus()
TextBox2.SetFocus
TextBox1.SetFocus
End Sub

Apparently it is a timing issue.

Thank you!
