\*\*EDIT: \*\*I got it figured out… it was casting… never knew I could cast so easily!!!

Thanks anyways!

Hey everyone… I have this code in my application…

```auto
var returned:Number = ExternalInterface.call("returnEntryCount");
nInterval = setInterval(upTo, 1000, returned);

```

“returned” is simply a number (integer to be precise)… but when I run my app I get this error:

```auto
Type mismatch in assignment statement: found Object where Number is required.

```

It looks to be some sort of casting problem, but I can’t understand why this won’t work… can anyone give me some advice here?

Thanks,
