Problems clearing an html text object

Wed, 13 Apr 2011 00:35:15 -0700

After I got this to work I copied the code in order to make a clear button / function. I've been having problems, even though the code seems to be identical. This is likely an obvious question, pardon my inexperience.

<html>
<head>
<title>Beer Counter</title></head>
<body><script language="Javascript">

var beers = 0
var output =""

function beer()
{
beers = beers + 1
output = document.getElementById('output')
output.value = beers
}

function clear()
{
beers = 0
output = document.getElementById('output')
output.value = beers
}

</script>

<input type='button' value='Crush' onclick='beer()'; /> Beer count:</input>
<input type='text' id='output' name='output'; /><br/>
<input type='button' value='Clear' onclick='clear()'; />
</body>
</html>
