I have these six static divs in my page and I want to create a button that updates a variable and adds a new div to the page. This is what I have so far:

```
function addSlot(){
   maxChecks = maxChecks+1;
   $("#list").append("<div id ='member7' class='member'></div>");
}

```

So this adds a div but the problem is the new div is always going to have an id of 'member7'. How do I make so that the next time the button is clicked, the next new div is member8, then member9, etc.?
