how to reflect the value of custom field within an array

hello,

i’m not sure whether i posted it at the right place, but i need immediate help with reclecting the value of a custom field on my index page. i have a theme, which shows the prices of items and calculates the discount. but now i have different items with different curencies. when i put the currency mark, i get divided by zero error, but then i had one more idea, and it was to reflect the currency mark (which is valued within a custom field) to the index just before the price. my theme has this code:

<?php $lang = array(‘firstprice’,’price’,’blabla’,’blala’,’see details’,’blabla’,’blabla’,’blabla’,’blabla’,’What customers say about’,’CURRENCY’,’blabla’,’blabla &raquo’,’Price Starting at’);?>

for that CURRENCY i need the theme grab the value of a custom field and show that there.. i couldn’t do that so far.. is that something possible?

thank you in advance!!
