That is because you have pasted some lines wrong (marked red below).
if strBio = "1" then
strSql = strSql & ", M_BIO = '" & ChkString(Request.Form("Bio"),"message") & "'"
end if
strSql = strSql & " WHERE M_NAME = '" & ChkString(Request.Form("Name"), "SQLString") & "' "
if strAuthType = "db" then
strSql = strSql & " AND M_PASSWORD = '" & ChkString(Request.Form("Password-d"), "SQLString") & "'"
end if
if strAUAnon = "1" then
strSql = strSql & ", M_AUHIDE = '" & ChkString(Request.Form("AUHide"),"") & "'"
end if
The above should be like this:
if strBio = "1" then
strSql = strSql & ", M_BIO = '" & ChkString(Request.Form("Bio"),"message") & "'"
end if
if strAUAnon = "1" then
strSql = strSql & ", M_AUHIDE = '" & ChkString(Request.Form("AUHide"),"") & "'"
end if
strSql = strSql & " WHERE M_NAME = '" & ChkString(Request.Form("Name"), "SQLString") & "' "
if strAuthType = "db" then
strSql = strSql & " AND M_PASSWORD = '" & ChkString(Request.Form("Password-d"), "SQLString") & "'"
end if
