It is not a js-file, I presume.

Show us some code.

Make the file include function Random() from the FAQ, and

var MyStuff = [
"Link 0",
"Link 1",
// ...
"Link 9",
"Dummy" ]

and

function getRand(X) { return X[Random(X.length-1)] }

then in your page

SomeLink = getRand(MyStuff)

Include the .js file in the usual manner, as in <URL:http://www.merlyn.

You may prefer to have one .js file for the code and others for data.

"Dummy" was included for ease of editing; it allows all the links lines
to be of the same format. If you omit it, omit also -1.

It's a good idea to read the newsgroup and its FAQ. See below.
