Ok i made the script for the Casino. Now im trying to make money. Im trying to make it so you start out with 10$. And a prompt Box will pop up at the beggining asking for your bid. If you choose "Yes" and the Number is Greater then 0.5. The amount you put in the prompt box will be awareded to you.

NOW, heres my question. How can i make it so if you put in any charcters that arnt numbers then an alert will pop up saying "some of that charcters you intered are not numbers".

heres what i got so far: by the way the variable "Bid" is my prompt Box.

if (Bid != ?) <<<<HERES MY PROBLEM!!
alert("some of that charcters you intered are not numbers")

Whats the script?

This should work:

if (isNaN(Bid))
alert("some of that charcters you intered are not numbers");

isNaN stands for is not a number. Here (http://www.devguru.com/Technologies/ecmascript/quickref/isnan.html) is some more info.
