Random number checking problem

[asylum24]

well here is my code that I have


shuffle=Math.ceil(Math.random()*2)
shuffle2=Math.ceil(Math.random()*4)
if(shuffle==1){
shuffle="hawaii";
}
if(shuffle==2){
shuffle="ua";
}

gallery_stage.loadMovie("pictures/" + shuffle + shuffle2 +".jpg");

trace(shuffle + shuffle2);


that works all fine and dandy except that i have these pictures and there are 4 hawaii pictures and only 2 ua pictures. and it loads everything correectly but whenever shuffle = something more than 2 and shuffle = 2 (like if shuffle =2 and shuffle2 = 4, it owuld load ua4.jpg, which doesnt exist) so how can I check to see if it is there and if its not, redo shuffle2?

anyhelp would be appreciated.

no ebcuase im not loading it into seperate movie clips its randomly picking if its a hawaii or a ua picture and hten randomly picking which picture it is with shuffle 2. and then combining the two to give me the file name which loads it into gallery_stage. its for a random background and hten im using the same pictures through out the site taht way i dont have to load the same picture again with just a diff. filename.

try something like this

createEmptyMovieClip("gallery_stage", 1);
myArray = [];
for (var i = 1; i<5; i++) {
myArray.push("hawaii"+i);
}
delete i;
for (var i = 1; i<3; i++) {
myArray.push("ua"+i);
}
function shuffle() {
return Math.round(Math.random());
}
myArray.sort(shuffle);
gallery_stage.loadMovie("pictures/"+myArray[0]+".jpg");

iono. im at home now and just arted typing stuff out and I think I came up with a solution.... tell me what youthink

shuffle=Math.ceil(Math.random()*2)

//declares how many pictures there are of (n) type
numOfPicsUA = 2;
numOfPicsHaw = 4;





if(shuffle==1){
shuffle="hawaii";
shuffle2=Math.ceil(Math.random()*numOfPicsHaw)
}

if(shuffle==2){
shuffle="ua";
shuffle2=Math.ceil(Math.random()*numOfPicsUA)
}

gallery_stage.loadMovie("pictures/" + shuffle + shuffle2 +".jpg");

trace(shuffle + shuffle2);
