When I run the following code I am getting the error 1004

"Method 'Range' of object '_Global' failed"

Dim rng as Range
with Worksheets("Sheet1").Columns(1)
set rng = .find(what:=Userform1.Textbox1.Text, _
After:=Range(A65536), _
LookIn:=xlFormulas, _
LookAt:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlNext, _
MatchCase:=False)
End with
If not rng is Nothing then
With Userform1
.Textbox2.Text = rng.offset(0,1).Value
.Textbox3.Text = rng.Offset(0,2).Value
' and so forth
End with
Else
msgbox Userform1.Textbox1.Text & _
" was not found"
