 * validation varieties:
 *****
 * validation initiated with following call in <FORM> tag:
 *   onsubmit="form_validate('formname','fieldname1,fieldname2','checktype1,checktype2','alertmsg1,alertmsg2')"
 * where formname is the value of the <FORM> tag's declared name
 * where the fieldname array corresponds to the actual field names to be validated
 * where the checktype array corresponds to the field names array in reference, and to the values of validation varieties
 * and where the alerttext array corresponds to both above arrays in reference, and to text descriptions for use in error alerts
 *****
 *  1 - test char string against null value
 *        expects fieldname, 1, string for alert text (i.e. "Username")
 *  2 - test string length against passed char lengths -- min and max
 *        expects fieldname, 2|lengthA|lengthB, alertmsgID (i.e. "2|4|8" for a string between 4 and 8 characters long)
 *  3 - test string match against two passed fields
 *        expects fieldnameA|fieldnameB, 3, alertmsgID (unless using non-custom alertmsg, then pass alerttextA|alerttextB)
 *  4 - test for selected option
 *        expects fieldname, 4, string for alert text (i.e. "Username") 
 *  5 - test for radio or checkbox selection
 *        expects fieldname, 5, alertmsgID
 *  6 - test email for format
 *        expects fieldname, 6, alertmsgID
 *  7 - test date for format (mm/dd/yyyy) and valid dateparts and optional test for date within future range
 *        expects fieldname, 7|dayrange, alertmsgID (i.e. "7|30" checks for a date no more than 30 days in the future)
 *  8 - test for numeric chars and against passed char length -- strips and returns only numeric string
 *        expects fieldname, 8|length, string for alert text (i.e. "Username") (i.e. "8|9" checks for a numeric string 9 characters long)
 *  9 - test for non-alphanumeric chars and against passed char lengths -- strips and returns alphanumeric string while testing against min and max lengths
 *        expects fieldname, 9|length1|length2, alertmsgID (i.e. "9|4|8" checks for a string between 4 and characters long)
 * 10 - test phone number for format (xxx-xxx-xxxx) -- strips and returns numeric string with phone number mask
 *        expects fieldname, 10, alertmsgID
 * 11 - subvalues check
 *
 *  13 - test url for format
 *        expects fieldname, 13, alertmsgID
 *  14 - test url or email for format
 *        expects fieldname, 14, alertmsgID
 *****
 * for forms located within a netscape layer, reference the formname as "layername.document.formname"
