need help with lists ...

Hi, I am struggling today with such basic widgets as lists are ... First - could any rebol guru explain me, what is face/paret-face item good for? So, I have following block of items: ["ATS" true] ["AUD" true] ["BEF" true] ["CAD" true] ["CHF" true] ["DEM" true] ["DKK" true] ["ESP" true] ["EUR" true] I wanted to display list of two columens - first one - the name of currency, the second one - if the currency should be put into output. I had following problems: 1) when creating the list dynamically, I couldn't prevent to display leds (representing true or false values) from being displayed thru all list till the bottom of the list face 2) I want my currency texts to be active. I have set active block, and I want to change the state of the let. Although I can see (printing to console) the state change, the led is not redisplayed. I tried another aproach using strings (switching between "Yes" "No"), but with no success ... Could anyone help me? Thanks, -pekr-
