Hey there, I’'ve hit a bit of a brick wall here. I am passing an array (Ticket) that contains lots of two-digit strings into a function. The function then needs to extract each number and also find the Math.floor/10 of the number.  
For some reason I am getting NaN for n but the number appears as expected :  
N: NaN number: 49

Here’s my code:

[AS]  
n = Math.floor(Ticket\*/10);  
trace("N: “+n+” number: "+Ticket\*);  
[AS]

if anyone could help I’d be really grateful.  
Thanks!
