Using variable in instance name

Hi guys,

My actionscript is a bit rust and i havent got round to learning acrion script 3 yet.

Im trying to create an animation that will cycle through letters (each of which have an instance name) by using a loop. I have a variable which it outputting the numbers i need if just used in a tract but i want to add it to the end of the instance name so that each instance scales one after the other.

Also if anyone knows any way of delaying each one by a few few seconds (or milliseconds if i remember the acrionscript unit of time correctly).
