I’m trying the add the data value of a selected combo box item (.35) to 1 using:

var theFringe:Number = \_root.calc.fringe.getValue();  
\_root.calc.fFringe.text = theFringe+1;

Returns: .351

Is there a way to convert the data from the comboBox to an integer so that when I add .35 +1 I’ll get 1.35?

Thanks in advance!

**Update:**  
I had to change my variable to:  
var theFringe:Number = Number(\_root.calc.fringe.getValue()); //added Number(…)
