(MX 04 Pro) Setting variables for an mc

What i need is to set some values for a few movie clips and then use them all at once. Eg, i’ll have 5 mcs in my movie, each with either variable = 1 or variable = 2 etc assigned to each of them differently. Then i want to run some code kinda like

if (the variable on mc_one < 4){
do some stuff
}

Im not sure if im going about it the right way, but i think its fairly obvious what im trying to do. Thanks in advance for your help. Merry Christmas, Happy Hanukkah, Happy Sunday etc etc.
