Show userform upon worksheet open

[ipbr21054]

Morning all,
As per title, in my workbook i have several worksheets.
On one worksheet when i click on the name tab i would like the userform to be shown.
I have clicked the tab in question,alt + f11, this workbook and then placed the following code there.
When i then click the tab in question i would expect the userform to be shown but i just see a blank worksheet & dont see any errors either.
What happens is when i open the workbook the userform is shown,but i would only like to see userform when i click the tab of the required worksheet.

What did i do wrong.
Many Thanks.

Private Sub Workbook_Open()LockPicking.Show
End Sub

My mistake and all sorted now.
I was using the OPEN command and should of used ACTIVATE command.

Thanks.
