An SQL Str Using IF Condition

Good morning


I am hoping some one can help me out with an SQL string I am having problems during to get working.

This is my code

Private Sub SearchRoleSeeking()

Dim db As DAO.Database
Dim qdf As DAO.QueryDef
Dim strSQL As String
Dim strFilterSQL As String
Dim txtBoxValue As String
Set db = CurrentDb
Set qdf = db.QueryDefs("qrySearch")

lstSearchResults = txtSearch1

If Me.txtSearch1.Value = "Temp" Then
txtBoxValue = 1
End If
If Me.txtSearch1.Value = "Perm" Then
txtBoxValue = 2
End If
If Me.txtSearch1.Value = "Temp or Perm" Then
txtBoxValue = 3
End If
strSQL = "SELECT tblPersonalInformation.[PersonalID],tblPersonalInformation.[Surname],tblPersonalInformation.[Forename],tblPersonalInformation.[DOB],tblPersonalInformation.[WantedRate],tblPersonalInformation.[WantedSalary],tblPersonalInformation.[Status],tblPersonalInformation.[RoleSeeking]" & _
"FROM tblPersonalInformation " & _
"WHERE tblPersonalInformation.RoleSeeking = ('txtboxvalue')"


qdf.SQL = strSQL
Me.lstSearchResults.RowSource = "qrysearch"

Set qdf = Nothing
Set db = Nothing

End Sub


let me try explain what I am trying to do.
I have a form where personal information is entered into. It has an option group that allows 3 choices.
I have made a form that I will use to search (the above code is from that.) What I am trying to do is if a person enters "Temp" into txtSearch1 then for the SQL statement to search "tblPersonalInformation.[RoleSeeking]" for the value 1.
If a person enters "PERM then for the statement to use 2 as the value for txtSearch1 and so on.

Can anyone help out with my task at hand.

Thanks everyone for your help.
