how do I call a variable created within a function from inside the function?

\<script\>  
function chk()  
{  
var [color=red]expression[/color] = /^[]?nill[]?$/i;  
if(document.form2.date1.value == “”)  
{  
alert(" Please enter the date or write nill")  
document.form2.date1.focus()  
}  
else if([color=red]expression[/color] != document.form2.date1.value)  
{  
alert(“done”);  
}  
\</script\>

not working.
