// FORM VALIDATION SCRIPTS
// JavaScript Document by Xpanxion, Inc.  11-29-2007

// entsub(): accepts ENTER to submit form on IE. Runs function submitform(). Add onkeypress="entsub();" to each input line.
// changeCase(frmObj): changes field to Proper Case where frmObj is form object (note: not value, but just object)
// Validate_Email_Address(obj): validates that field is proper email address. obj is field value. returns false if not valid.
// clearfield(eventobj): clears background highlight from field. Add onblur="clearfield(this);" to each input line.
// highlightobject(eventobj): highlights background of field object. Use in validation scripts to highlight wrong fields.
// highlight(e): automatic highlight of background of field objects. Add onKeyUp="highlight(event)" onclick="highlight(event)" to form tags. Make sure to set variable highlightcolor="#cccccc" in script tag in main document.
// Phone number formatting: add to input tag - onkeydown="javascript:backspacerDOWN(this,event);" onkeyup="javascript:backspacerUP(this,event);" 
// ValidPhoneNumber(obj): returns false if obj is not a valid 10-digit phone number
// *** SAMPLE submitform() function AT BOTTOM
