I'm trying to add a validation on a box within a userform that I am working on. I want to make sure that if the user selects the value Direct within a combo box within the userform, they will be unable to leave the TxtAmt box empty. They will have to enter a numeric value within the box if Direct is selected. I thought if I added 
If Me.cboDirectIndirect.Value = "Direct" Then
      Me.TxtAmt.Text <> ""
End If
Users would no longer be able to leave the amount box blank. Unfortunately, I cannot even get to the testing phase, because I encounter a Compile Error: Expected expression, and the <> operator is highlighted. I also tried to write it using 
 Me.TxtAmt.Value
instead of 
 Me.TxtAmt.Text
But that didn't work either. Can anyone tell me what I am doing wrong? I added the if statement at the end of the sub-query. Here's the entire sub-query:
Private Sub txtAmt_Exit(ByVal Cancel As MSForms.ReturnBoolean)

If Me.txtAmt.Value = "" Then
        Me.OverShortAmt.Caption = ""
        Cancel = True
        MsgBox ("Amount Box cannot be empty! Please enter in a dollar amount in Numeric Form.")
        Exit Sub
    ElseIf Not IsNumeric(Me.txtAmt.Value) And Me.txtAmt.Value <> "" Or Me.txtAmt.Value = " " Then
        Cancel = True
        MsgBox ("Please enter in a valid numeric amount! NO TEXT OR SPACES!")
        Exit Sub
    End If

    With Me.OverShortAmt
        If Me.txtAmt.Value < 0 Then
            .BackStyle = fmBackStyleTransparent
            .BackColor = rgbAquamarine
            .ForeColor = vbRed
            .Caption = "Short"
            .Font = Bold
        Else
            .BackStyle = fmBackStyleTransparent
            .BackColor = rgbWhite
            .ForeColor = vbBlack
            .Caption = "Over"
            .Font = Bold
        End If
    End With



If Me.txtAmt.Value = "" Then
    Me.OverShortAmt.Caption = ""
End If


If Me.cboDirectIndirect.Value = "Direct" Then
    Me.txtAmt.Text <> ""
    
End If

End Sub
I appreciate any and all help. Thanks!
