hi everybody, maybe someone can help me.  
my problem is:  
I have a number of checkboxes, which are keys with the following code :  
key1.onRelease = function() { myVar1 = “1”};  
key2.onRelease = function() { myVar2 = “16”}  
key3.onRelease = function() { myVar1 = “24”};…etc  
variables are numbers 0-6,  
I want to display in a dynamic textfield all these values in order, that means  
the return must be : 11624…  
I have tryed with :  
myCode = myVar1+myVar2+myVar3+…, myCode is the var name of the dynamic textfield, but the result is NaN in FP8 and 0 in FP6. where is the mistake, or how must I proceed? thank you in advance.
