Hey Guys, could do with some help!

I've been making some slow progress in modifying the way that specials display as you can see here: http://www.appliancesfirst.co.uk/

What I am trying to do now is change the way in which the prices are displayed to try and make them more readable. What I am trying to achieve is the following:

Was: £This Price
Now: £This Price
Saving: This%

On three lines, and adding the words Was: and Now:

Two things: I am getting a little worried as the mods I am making are not "Zen-like". And also, my lack of php skills means that I am having trouble finding where to insert the "Now" text AND the following colons.

So, I have been modifying functions/functions_prices.php [can someone confirm that the overrides system does not work in this folder] On line 224 have changed this code

$show_normal_price = '<span class="salesText">' . Was .' ' . '</span>'.'<span class="normalprice">'

How do I display the : , I've tried just about everything I can think of but just keep generating errors!

Where do I insert the Now: , same question applies about the :

And where do I put the <br>'s. As you can see I've added one in /languages/my_template/english.phpin define('PRODUCT_PRICE_DISCOUNT_PREFIX','<br> Save:&nbsp;'); for the save: text.

I've been playing code detective all day - by 7:30am I was way out of my depth, its now 23:34 and the water is getting very deep!

Many thanks.
