[HELP] Performance Issue

[iPollo]

i'm experiencing lag running this code. Some one can help me to improve it or give me the hint to follow the best way to do it? in short the code does: it takes all elements in the determined range and checks if it is a collectable item, after that it adds the values of that item in a temporary table. When the player is next to the item (or items) the item's icon is drawn on it. Everything works ok, but the fps drops and it frozes slightly
