hope you can help me

i have made a menu, now i try to give them different bg colors on release.

this works good. i made 5 variables with the rgb values etc.

now i want to make the colors random

to test this before i make the random function i made this:

on (release) {
/:farbegeben = Number (/:color add 4);
_root.actions.farbe.setRGB(/:farbegeben);
}

the variable output is this

_level0.farbegeben = 1.#QNAN

instead of

_level0.farbegeben = 16751052 or 0xff99cc


the variable is /:color4

thx for trying to help me
