I've probably read the problem entirely wrong. : )If so, you can create a list and shuffle its contents. I used text variables, but you could use an array if you're on the 5.0 bus.In this example, you'd set the value for [totalNumbers] to the number of SWF files in your selected folder. [text]totalNumbers=30[/text][loop start=1&end=[totalNumbers]] [text]number[index]=[index][/text] [/loop][loop start=1&end=[totalNumbers]] [math show=F]pick=floor([random format=float]*[totalNumbers])+1[/math] [text]temp=[text]number[index][/text][/text] [text]number[index]=[text]number[pick][/text][/text] [text]number[pick]=[temp][/text] [/loop][loop start=1&end=[totalNumbers]] [index]: [text]number[index][/text]
