Hi
Right i think the file you need is skin/YOUR SKIN/customer/main/products_t.tpl
Find following (Line 113 approx) (it may be slightly different as i have changed it and can't remember what it was before

):
Code:
{if $product.appearance.has_price}
<div class="price-row">
<span class="price">{$lng.lbl_our_price}:</span> <span class="price-value">{include file="currency.tpl" value=$product.taxed_price}</span>
<span class="market-price">{include file="customer/main/alter_currency_value.tpl" alter_currency_value=$product.taxed_price}</span>
</div>
Change to:
Code:
{if $product.appearance.has_price}
<div class="price-row">
<span class="price">{if $product.is_variants}{$lng.lbl_priced_from}:{else}{$lng.lbl_our_price}:{/if}</span> <span class="price-value">{include file="currency.tpl" value=$product.taxed_price}</span>
<span class="market-price">{include file="customer/main/alter_currency_value.tpl" alter_currency_value=$product.taxed_price}</span>
</div>
I didn't bother changing it in the product details as it didn't really make sense to, as when you pick a variant it is that price so doesn't need to say price from.
Let me know if that works and if not i will look into it further.
Cheers
Richard
PS: Note to the TEAM - this really should be already in the main distribution!!
