Runtime error 3075 can't figure it out - ms-access

Question

I'm trying to do an insert on a button click event and I keep getting a runtime error of missing operator in query expression my query looks like the following. Any ideas?
Private Sub CmdAdd_Click()
Dim strSql As String
strSql = "INSERT INTO Current_Costs(PO_Number,Lineitemid,Capital_detail,CapitalID,GL_Number,Cost_Type,Cost_Center,Cost_cat,Item_Cost,PO_Date)" & _
" VALUES (" & Me.txtPONum & "','" & _
Me.cmbCapDetail & "','" & _
Me.cmbCapDetail.Column(1) & "','" & _
Me.txtCapID & "','" & _
Me.txtGLNum & "','" & _
Me.cmbCostType & "','" & _
Me.txtCostCen & "','" & _
Me.cmbCostCat & "','" & _
Me.txtCost & "','" & _
Me.TxtPODate & "')"
DoCmd.RunSQL strSql
i have a similar query that has the same issue and i cant see the problem
CurrentDb.Execute ("UPDATE Current_Costs " & _
"SET PO_Number='" & Me.txtPONum & "'" & _
",Lineitemid='" & Me.cmbCapDetail & "'" & _
",Capital_detail='" & Me.cmbCapDetail.Column(1) & "'" & _
",CapitalID='" & Me.txtCapID & "'" & _
",GL_Number='" & Me.txtGLNum & "'" & _
",Cost_Type='" & Me.cmbCostType & "'" & _

",Item_Cost='" & Me.txtCost & "'" & _
",PO_Date='" & Me.TxtPODate & "'" & _
"WHERE LineItemPOID=" & Me.txtID.Tag)

Answer 1

This
" VALUES (" & Me.txtPONum & "','" & _
Is short one quote, it should be
" VALUES ('" & Me.txtPONum & "','" & _
Write your sql in a string, it makes it easier to see the problems:
strSql = "UPDATE Current_Costs " & _
"SET PO_Number='" & txtPONum & "'" & _
",Lineitemid='" & cmbCapDetail & "'" & _
",Capital_detail='" & cmbCapDetail.Column(1) & "'" & _
",CapitalID='" & txtCapID & "'" & _
",GL_Number='" & txtGLNum & "'" & _
",Cost_Type='" & cmbCostType & "'" & _
",Cost_Center='" & txtCostCen & "'" & _
",Cost_cat='" & cmbCostCat & "'" & _
",Item_Cost='" & txtCost & "'" & _
",PO_Date='" & TxtPODate & "'" & _
" WHERE LineItemPOID=" & txtID
Dim db As database
Set db = CurrentDB
db.Execute strsql dbFailOnError
You were missing a space before WHERE and you had an unmatched parenthesis.
Consider using parameters: End of statement error
