Type:
User Input form

Problem #1:
Multiple search criteria is partially working. AppDate.Value works
fine, however the following error comes up when it reaches the second
criteria, AppDate.Value. The columns (F & G) are single numbers and
are entered via a drop down list via another input form.

[F: Month] [G: Day]
7 1

Error:
Run-time Error (91)
Object variable or With block variable not set.

Problem #2:
I have yet to find a way to set the row with the found results and the
first cell as the active cell to start editing. I can set the offset
value easy enough, however the cell number is dynamic and most often
will not be the same.

Code:
Private Sub Search_Click()
Dim wks As Worksheet
Dim wks2 As Worksheet
Dim FoundCell As Range
Dim FoundCell2 As Range

Set wks = Worksheets("Appointment Log")
If Me.ClientNum.Value = "" And Me.AppDate.Value = "" Then
MsgBox "You must enter a Client # and Appointment Date it was
set for!"
Exit Sub
End If

With wks
With .Range("C:D") '*** Columns to look in, unable to set to a
single column? ***'
Set FoundCell = .Cells.Find(what:=Me.ClientNum.Value, _
after:=.Cells(.Cells.Count), _
LookIn:=xlFormulas, _
Lookat:=xlPart, _
searchorder:=xlByRows, _
searchdirection:=xlNext, _
MatchCase:=False)
End With
End With

With wks2
With .Range("F:G") '***Columns to look in.***'
Set FoundCell2 = .Cells.Find(what:=Me.AppDate.Value, _
after:=.Cells(.Cells.Count), _
LookIn:=xlFormulas, _
Lookat:=xlPart, _
searchorder:=xlByRows, _
searchdirection:=xlNext, _
MatchCase:=False)
End With
End With

If FoundCell And FoundCell2 Is Nothing Then
MsgBox "Not found, please try again."
Else
MsgBox "Found it! Input Fields are now enabled, please enter
your results below."
DealClosed.Enabled = True '1st Cell to be edited, Column L
DealClosed.SetFocus
ClientClosed.Enabled = True '2nd Cell to be edited, Column M
Showed.Enabled = True '3rd Cell to be edited, Column N
Closed.Enabled = True '4th Cell to be edited, Column O
Notes.Enabled = True '5th Cell to be edited, Column P
FrontGross.Enabled = True '6th Cell to be edited, Column Q
BackGross.Enabled = True '7th Cell to be edited, Column R
SaveB.Enabled = True '8th Cell to be edited, Column S

End If

End Sub

Thanks in advance for any help provided, it is greatly appreciated!

(ClientNum.Value is the correction)
