Can't Search data from table

[billa856]

Hi,
My project is in MS Access.
In that I have one Form(Search) which I am using for Search data in my Table(PRODUCTION).
Now in this form I have one Combobox(PalletNo) and one button(Search)
When I select an item from combobox and click on Search button then it will generate report based on search criteria.
In my combobox items are like
PFI
LPL
LPL/AVON
LPL/EL
LPL/PFI
VIC
ZERTH
etc
Now when I select anything except LPP/PFI
then it will shoe me result whatever I nedd.
But when I select LPL/PFI then it will show me error that Data Tyoe Mismatch in Criteria Expression.
Only for perticular item it shows me Error.
Even I check Table also but there is no such problem in it also.
I think there is /P in LPL/PFI so may be because of that it will show error.Or is there any other problem?
I am using this code on click event of Search Button

Private Sub Search1_Click()
On Error GoTo Err_Search1_Click

Dim stDocName As String

stDocName = "PRODUCTION1"
DoCmd.OpenReport stDocName, acViewPreview, , "PRODUCTION.CustomerCode = '" & Me!CustomerCode_Combo1 & "'"

Exit_Search1_Click:
Exit Sub

Err_Search1_Click:
MsgBox Err.Description
Resume Exit_Search1_Click

End Sub

Plz Help Me.
Thanks.
