Quick SQL Sintax Help

So for reason I would rather not discuss I have to modify a really old asp page... They need it to add some simple data to a table in a SQL Server 2008 database...

So far everything is going great but I'm having a sintax error on the command send to the database wich is:

SQLTxt = "INSERT INTO Tbl_HRSugerenciasSSA(nombreEmpleado, ubicacion, sugerencia) VALUES (" & nombempleado & ", " & SAL_UBICACION & ", " & SAL_DESCRIPCION & ")"

Mind helping me out plz???
