Making the Attribute Price Displayed shown inc. Tax

[Guest]

We show all product prices on our site inc tax (as selected from the config page). When we have attrubutes that effect price we add these via the cataolg option with the additional cost ex tax - problem is these are shown as such on the site (i.e ex Tax and we need them top be shown inc Tax - the calcutaltion of price thougyh at checkout is correct so this is just a 'display' change' and we need either:-

 

1) To show the attrubutes prices inc Tax.

 

or

 

2) Show the totol price of the item (including the attribute selected and tax) - which is okay for us as products only have 1 price effecting attribute.

 

Any ideas, I am sure I am not the first to ask, and surely as you can select this option in Admin ofr noraml products, there is a simple code change to the product_info.tpl.php or similar that will make this work.

 

All help appreciated - I cannot load any more products to our store (as they all now have attrubutes) until I can get this fixed.

 

Many thanks,
