Your first problem is that you're calling the function with a string, not a number. '1' + 1 is '11', but 1 + 1 is 2.

Your second problem is that you're not saving the new value anywhere; you just keep calling the function with 1. You need to use a variable.

Here's the fixed code:

<script>
var valur = 1;
function pag()
{
    ++valur; // add one
    alert(valur);
}
</script>

<a href="javascript:pag();">More</a>
