[AS3] Combobox numerical values

[Nando88]

I currently have 2 combo box on stage. I have added all the labels and some data to these combo boxes, through properties tab. what I want to do is a mathematical operation with the numerical values assigned to each label in the combo box, so I can for example multiply the numerical value assigned to a label in the first combo box and multiply it by another numerical value in the second combo box.
How can I do this?
Thanks in advance!

I found the answer to my problem:

var out1:int;
out1=Number(cb2.selectedItem.data) + Number(cb1.selectedItem.data);

Where cb1 and cb2 are combo boxes.
