//---------------- FORM VALIDATION
/*
[OVERVIEW]
Simple validation. After submitting, it alerts the user
with a list of missing elements, at the same time colours the
form fields needing attention.

[CALL]
This function takes two arguments. Firstly, the form object.
Secondly, an array of information needing validating. The format
for the array is simple.

var myArray = new Array ("myEmail,eml,Please enter your email address")
if (myvalidate(objForm,myArray)) objForm.submit();

1. Field Name
2. Validation Type*
3. Alert Message

*The validation type has a few pre set types to make life easy.

1. Required:	req		(Forces something to be entered)
2. Email:		eml		(Forces the '@' and '.' characters)
3. Number:		num		(Forces an integar type)

If some more custom needs validating, you can put that code in instead.
Example: "myPostcode,f.myPostcode.length!=4,You must have a 4 digit password"
