problem updating SQL bit field? No error, but isn't updating?

It appears that you can't use this:

MM_editCmd.Parameters.Append MM_editCmd.CreateParameter("param1", 5, 1, -1,
MM_IIF(Request.Form("liveorder"), -1, 0)) ' adDouble

...with an SQL bit field. It has to be numeric, like this:

MM_editCmd.Parameters.Append MM_editCmd.CreateParameter("param1", 5, 1, -1,
MM_IIF(Request.Form("liveorder"), Request.Form("liveorder"), null)) '
adDouble

..and it works! Weird!
