Element not found - VbWindow

[edj1]

I hope someone can help me with this one.

The way my script is working is one window (parent) opens another window (child).
Then I am trying to clear and write data into the Child Window.
The coding is as follows;

Code:

VbWindow("Child Window ").VbEdit("FieldOne").Type micBack

As soon the script hit this line I am getting the following error message “Element not found”
I even tested, using the script below, if QTP sees the window/filed and it works

Code:

If VbWindow("Child Window").VbEdit("FieldOne").Exist(5) Then
MsgBox "I can see the Child Window and FieldOne"
End if

May someone let me know what I am doing wrong?

Thanks
