Hi, I programming a calculator, I get data on Yahoo Finance ( [http://www.rafaelvega.info/calcular-cambio-de-divisas/](http://www.rafaelvega.info/calcular-cambio-de-divisas/) ), but sometimes I get this error “NaN”

I need some orientation, thanks

You can download the file .fla here

My calculator is working in this link  
[http://www.tudineroefectivo.com/calculadoratde.html](http://www.tudineroefectivo.com/calculadoratde.html)

This is de most important code in the flash, what is wrong?

Thanks
