Random from multiple arrays

Question

I'm trying to generate a random picture half the time from
one array and half the time from another array.
I've get as far as this and it doesn't work. Any help would
be useful
var ranArrays: Array = new Array ("bluePixs", "redPixs");
var bluePixs:Array = new Array ("bluePix1.swf",
"bluePix2.swf", "bluePix3.swf");
var redPixs:Array = new Array ("redPix1.swf", "redPix2.swf",
"redPix3.swf");
function randomBackground(){
var randomArray = random (ranArrays.length);
var randomNumber = random (randomArray.length);
_root.pix.loadMovie (randomArray[randomNumber]);
randomBackground();

Hi,
Your SQL would be something like:
SELECT M.MONEY, DRINKS.NAME, DRINKS.PRICE, F1.PRODUCT, F1.PRICE, F2.PRODUCT, F2.PRICE, DESERT.PRODUCT, DESERT.PRICE
FROM MONEY M
CROSS JOIN DRINKS
CROSS JOIN F1
CROSS JOIN F2
CROSS JOIN DESERT
WHERE DRINKS.PRICE + F1.PRICE + F2.PRICE + DESERT.PRICE <= M.MONEYThat may return multiple results - as there may be a number of combinations less than your MONEY value. You can restrict this to return just one:
SELECT M.MONEY, DRINKS.NAME, DRINKS.PRICE, F1.PRODUCT, F1.PRICE, F2.PRODUCT, F2.PRICE, DESERT.PRODUCT, DESERT.PRICE
FROM MONEY M
CROSS JOIN DRINKS
CROSS JOIN F1
CROSS JOIN F2
CROSS JOIN DESERT
WHERE DRINKS.PRICE + F1.PRICE + F2.PRICE + DESERT.PRICE <= M.MONEY
AND ROWNUM = 1As you then only want to return a single string for display to the user, you will have to concatenate the items found into a single string:
SELECT DRINKS.NAME || ' ' || DRINKS.PRICE || ' ' || F1.PRODUCT || ' ' || F1.PRICE || ' ' || F2.PRODUCT || ' ' || F2.PRICE || ' ' || DESERT.PRODUCT || ' ' || DESERT.PRICE X
FROM MONEY M
CROSS JOIN DRINKS
CROSS JOIN F1
CROSS JOIN F2
CROSS JOIN DESERT
WHERE DRINKS.PRICE + F1.PRICE + F2.PRICE + DESERT.PRICE <= M.MONEY
AND ROWNUM = 1Obviously, you would want to replace the spaces (' ') with something more meaningful to the user
