Run-time error 91 object variable or with block varialbe not set

In Microsoft word I am recieving the Run-time error 91. this is the problem I put the code into a word document all by it's self and it works fine, when I moved the code over to my actuall project i started receiving this error and I can not figure this out. Does anyone have any suggestions? I am really stuck on this.

[code]
Private Sub Document_Open()
Application.WindowState = wdWindowStateMinimize
UserForm1.Show vbModeless
End Sub
[code]

yes it it's the userform1.show vbmodeless it debugs on, but only in my actual project. if i put the code in a document by it's self it works great.

Yes,

I removed the code from the userform and I am no longer receiving the error. But now it's not doing what I wanted it to do. Which is hide the word program it is running from. It hides until you open another word document. then it appears and if you minimize it you lose the userform. I am not understanding why it works when it's by it's self but not when I put it in my actual project. any thoughts on that?

That was not me - that was the person I am working with on this project. She has her sites she uses and I have mine. She didn't tell me she posted for assistance.

I found the problem - It was my mistake - thank you Norie for your assistance it was the information that you provided that brought my error to light. I had forgotten I changed the name of the object, So I was not referance the correct object in my project. I changed the name back to ThisDocument and now everything is working great. Again Thanks a million for your assistance.
