/*
***** val_integer(field)
	ENTRY TIME: Checks to be sure field is an integer.
	If not, displays error message and selects field.

***** val_range(field, minNbr, maxNbr)
	ENTRY TIME: Checks to be sure field is an integer and within a range.
	If not, displays error message and selects field.

***** val_email(field)
	ENTRY TIME: Very BASIC test to confirm that e-mail address looks right.
	If not, displays error message and selects field.

***** checkout_val_email(eTest)
	CHECKOUT TIME: For use at submission time. Validates e-mail address.
	Returns "ok" or "no".

***** val_phone(field)
	ENTRY TIME: Allows only characters used in phone numbers -- 0123456789()- .
	If invalid characters are present, displays error message and selects field.
	SEE CHECKPHONE.

***** checkPhone(myTemplate,theNumber,myLocation)
	ENTRY TIME: Validate that a phone number conforms to a template.
	Send the template, the value, and the location to return to if there's an error.
	If not, display error message and select field.

***** checkNumber(myTemplate,theNumber,myLocation,myNumType)
	ENTRY TIME: Validate that ANY number conforms to a template.
	Similar to previous, except also send a description of the field for use
	in the alert box.
	If number is incorrect, display error message and select field.

***** checkNumberCheckout(myTemplate,theNumber)
	CHECOUT TIME: Similar to previous.
	9=Any number  Other characters play themselves
	USAGE:
	if (checkNumberCheckout('FORMAT',document.forms[0].FIELD.value)>0) {
		missingInfo += "\n  -  MESSAGE.";
		nbrOfErrors++;
	}
	Returns 0 if field is empty or number is OK, 1 if number is no good.

***** email_ok(myEmail)
	CHECKOUT: Yet another e-mail test.
	Pass it the e-mail address value.
	Returns "approved" value:
   0 = OK
	+1 = None or too many @ signs
	+2 = No dot following the @ sign
	+4 = Not enough characters after the final dot
	+8 = Invalid characters present
	+16= No user (just a domain)

***** validate_2part_date(myCardMonth,myCardYear)
	CHECOUT: Determines wither a month-year date (2 fields) is valid.
	Returns "missingInfo" -- if blank, date was OK.

***** warnView()
	Displays standard warning before showing preview.

***** textCounter(field, countfield, maxlimit)
	Displays a running counter for data entry. Halts entry
	when maximum number of characters have been entered for field.
	INPUT FIELDS USAGE:
	Replace ALL CAPS names with appropriate values
	<input type="text" name="FIELDNAME" size="MAXIMUM"
	onFocus="textCounter(this.form.FIELDNAME,this.form.remLen,MAXIMUM);"
	onKeyDown="textCounter(this.form.FIELDNAME,this.form.remLen,MAXIMUM);"
	onKeyUp="textCounter(this.form.FIELDNAME,this.form.remLen,MAXIMUM);">
	DISPLAY FIELD USAGE
	<input readonly type=text name=remLen size=4
	maxlength=3 value="" tabindex="-1"> characters left</font>
	NOTE: readonly works only with MSIE and NETSCAPE 6
	NOTE: tabindex="-1" works only with MSIE and NETSCAPE 6

***** checkLanguage()
	Figures out what language the BROWSER is set to and returns
	that value to "document.forms[0].language_name.value".

***** find_special_characters()
	Examines all text field in document.forms[0] to determine
	whether they contain any characters above 127.
	Returns "yes" or "no".

***** upperMe(field) and lowerMe(field)
   Typical use: onBlur="lowerMe(this)"
   Returns lower (or upper) case to field.

***** validateURL(myURL, noHTTP)
	Typical use: if (validateURL(document.forms[0].website.value, false)==false) ...
	Returns true if URL is OK, false if it is not

***** isAllCaps(myText)
	Typical use: if (isAllCaps(document.forms[0].FIELD.value)==false) ...
	Returns true if field is all caps.
