Lifecycle of an Array

Hi,

me problem is, that I want to use an Array to store data on it and use it lateron in serveral functions.
I declared an array like this:

<BODY>
<script language="JavaScript">

</script>

Lateron I want to use this Array in another function, which I declared in the <HEAD> section.

It looks like:

function sammle(x)
{
var x;
/*document.write("bin drin");*/
document.write(i);

/*MeinArray[i]=x;
document.write(i);
document.write(MeinArray[i]);*/

if ( i == 100 )
{
document.write("HaltStop 100");
}
if ( MeinArray[i] == "Enter" )
{
document.write("Berechne");
}
i++;
}

Now, at runtime I get the answer that "MeinArray" is not definded
in this particlure function.

I knew, that variable must be declared as globol for to use it
in all "places". But I cant find any hint what's about array declarations. Is it possible to use the same array in several functions, whithout losing data?

Best Regards

It's entirely possible. There SHOULD be no loss of data.
Do you think you could give us a link to the page in question?

declare the array as the first thing inside your script tags, this will ensure that it is defoned before anything tries to acess it.

as i think you are doing this:

Trying to acess array

defining it

which should be the other way round.

Where did you populate the array?
Maybe you access it before you populated it.

Hi,
thanks for Your time in spending to answers my Question.
With Your Help I found my mistakes. First, the was a logical
error , but the main reason, the script not work is, that I called the array, before I hat assigned it.

Thefore many thanks and
best regards
