It looks like you moved these validations to the onchange of the select box:
WAValidateCD(document.forms[0].accounttype,document.forms[0].dmxCalendar_1,false);WAValidateEN(document.forms[0].accounttype,document.forms[0].dmxCalendar_1,false);WAValidateCD(document.forms[0].accounttype,document.forms[0].dmxCalendar_2,false);WAValidateEN(document.forms[0].accounttype,document.forms[0].dmxCalendar_2,false);WAValidateEN(document.forms[0].accounttype,document.forms[0].FreeTrial,false)
You would want to undo that change. Then you would want to put in if statements similar to this:
if(<account type> == "m") WAValidateCD(document.forms[0].accounttype,document.forms[0].dmxCalendar_1,false);
