Reset to default 3

It'd be easier to do this in jQuery, but here it goes with POJS:

js:

var value = 0, 
tb = document.getElementById("tb"),
progress = document.getElementById("progress"); //store these, it's better
function increase(){ 
  value++;// same as value += 1, but better
  if(value>=100) value = 100;//keep it under 100%
  tb.value = value;// set the value of the text field     
  progress.style.width = value + "%";// set the width of the progress bar
} 
function decrease(){ 
  value--;
  if(value<=0) value = 0;//keep it over 0%
  tb.value = value; 
  progress.style.width = value + "%";
} 

document.write is janky, so I ditched that & put the bar in the markup.

html:

<button onclick="increase()">Add</button> 
<button onclick="decrease()">Minus</button> 
<input type="text" id="tb"> 
<div id='meter'><div id='progress'></div></div>

css:

​#meter {border:1px solid #000;width:100px}
#progress {background:#333;height:10px;width:0%}​
