DoCmd Open form error on filter

[Lynch225]

Hey all, everytime I open the form Clickform with a button, I keep getting a runtime error 3464- data type mismatch in criteria expression with the DoCmd line highlighted.

Basically I have a group of checkboxes (Check1, Check2, etc.) on a form called Check, and the code filters through the checkboxes to see which ones are checked. Once the user clicks the button (called Command0), it opens up the Clickform and applies a filter based on the checkboxes. For instance, if Check3 and Check4 are highlighted, then the Checkform will be filtered on the records where Door=4 or Door=5. Here's my code:

Option Compare Database
Option Base 1

Private Sub Command0_Click()

Dim Ctrl As Object, i, j, RecsChose, ThisChkbox, ErrMess, sqlStr, sqlPl
Dim Narr() As Variant

ThisChkbox = 0
i = 0

For Each Ctrl In Me.Controls
    If (Ctrl.ControlType = 106) Then
        ThisChkbox = Ctrl.Value
        If ThisChkbox Then
        i = i + 1
        ReDim Preserve Narr(i)
        Narr(i) = Ctrl.DefaultValue
        End If
    End If
Next

If i > 0 Then
    For j = 1 To UBound(Narr) - 1
        RecsChose = RecsChose & "Trailers_Unloading_LA.Door=" & Narr(j) & " OR "
    Next
    RecsChose = RecsChose & "Trailers_Unloading_LA.Door=" & Narr(j) & ";"
    sqlP1 = "SELECT Trailers_Unloading_LA.Door, Trailers_Unloading_LA.Trailer_Number, Trailers_Unloading_LA.LA01, Trailers_Unloading_LA.LA02, Trailers_Unloading_LA.LA03, Trailers_Unloading_LA.LA04, Trailers_Unloading_LA.LA05, Trailers_Unloading_LA.LA06, Trailers_Unloading_LA.LA07, Trailers_Unloading_LA.LA08, Trailers_Unloading_LA.LA09, Trailers_Unloading_LA.LA10 FROM Trailers_Unloading_LA WHERE "
    sqlStr = sqlP1 & RecsChose
    Else
    ErrMess = MsgBox("No trailers are being unloaded", vbOKOnly, "Status")
End If

Debug.Print sqlStr

DoCmd.OpenForm "CheckForm", acNormal, sqlStr, , acFormReadOnly, acWindowNormal

End Sub

Any ideas why this is not working? I can't seem to figure it out after scouring the internet looking for reasons why it might not be working..

Is Door a string? If so you need to surround the values in quotes.

Ahhh yes, something so simple. Thanks rabbit.

Sure thing, good luck.

Ben, Here's a couple of links for you.

1. Quotes (') and Double-Quotes (") - Where and When to use them
2. When Posting (VBA or SQL) Code

A should prove helpful with similar issues in future.
B I would like (as a moderator) to ask you to read before posting code again. Never worry. You'll get much more from it than we will - it's a win-win for all. Using code with no Option Explicit line is just a recipe for problems for you.
