Access Code to check data for acceptable answer

Hello Experts.

I need your help with the below code.  I'm trying to have this code evaluate the content of an imported text field.  The field can only have 1 of 5 possible results (yes, y, no, n, and Null).  The evaluation should not be case sensitive.

The code below is giving me a Type mismatch error.

Thanks in advance for your help.

Function chkYesNo(ByVal varValue As Variant) As Boolean
    'Check if varValue is Null, Y, Yes, N, No
If varValue = "yes" Or "y" Or "no" Or "n" Then
    chkYesNo = True
Else
    chkYesNo = IsNull(varValue)
End If
       
End Function

You always have to repeat the field you are comparing to.
If fldA = "yes" OR fldA = "n" or fldA = "no"..

Once there gets to be more then three options, a Case statement is usually simpler to read.
Function chkYesNo(ByVal varValue As Variant) As Boolean
    'Check if varValue is Null, Y, Yes, N, No
Select Case varValue
    Case "yes", "y", "no", "n"     
        chkYesNo = True
    Case Else
        chkYesNo = IsNull(varValue)
End Select       
End Function

Your if statement isn't quite right.
Function chkYesNo(ByVal varValue As Variant) As Boolean
    'Check if varValue is Null, Y, Yes, N, No
If varValue = "yes" Or varValue ="y" Or varValue ="no" Or varValue = "n" Then
    chkYesNo = True
Else
    chkYesNo = IsNull(varValue)
End If
       
End Function
