Access DB Update Problem

I have this code:

set con=server.CreateObject("ADODB.connection")
set cmd=server.CreateObject("ADODB.command")
cmd.ActiveConnection=con
cmd.commandtype=1
con.open "DSN=myDSN"

cmd.commandtext="UPDATE Members SET Members.PName='"& updname &"' where Members.PName='"& editName &"';"
cmd.execute

Everything works, I'm not getting an error... I even went to access, made a custom query with that command string, and it did update it. Only after I run the code is not doing a thing. This is the exact type of code I used on INSERT queries, and it worked just fine. The variables are right too, I added a response.write with them, they work just fine.
