Question:
How do I change the value of a variable using onmouseover.

Welcome aboard rogerelaine, you need a variable that is global in the document, like


<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01  
Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html lang="en"> 
<head> 
 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> 
 <title>Untitled</title> 
<script type="text/javascript"> 
var myVar = 0; 
function testVar() { 
 alert('myVar value is ' + myVar); 
 return false; 
} 
</script> 
</head> 
<body> 
<p><a href="test.html" onMouseOver="myVar=5;">Change to 5</a></p> 
<p><a href="test.html" onClick="return testVar();">Test the variable</p> 
</body> 
</html>
