Input ===> this.form (the form Object to be checked)
Output ==> Boolean result (true/false)

The form element should have these properties :
{
	validate --> either 1 or 0 (check or not).
	regEx --> the first regular expression.
	regEx2 --> the second regular expression.
		*(note)--> the check is regEx or regEx2 but not both.
	caption --> the text you want the user to get.
}

An example of a regular expression :
{
	(.*@{1}.*\..*) --> checks the email to be valid.
	(.{5,7}) --> any text at least 5 chars long but less then 7
	([0-9]) --> just the numeric values.
	(.+) --> any value	(= not empty)
	Note: You don't have to put regEx, if none is present the field is checked to have something.
	Note: You can read all about Regular Expressions in the MSDN Library.
}

** <select name="a3" validate=1 caption="select?!" regEx="([1-9])">
**
** <input type="radio" name="a2" value="1" validate=1 caption="radio" regEx="([1-2])">yes&nbsp;&nbsp;
** <input type="radio" name="a2" value="2" >no&nbsp;&nbsp;radio<br />
