Can anyone tell me how retrieve a calculated value of a variable from another function:

Sorry for the silly example but:

<head>

<SCRIPT LANGUAGE="JavaScript">
var estimate = 0;

function total1 (){
estimate = 55;
}

function revisedtotal2 () {

estimate = estimate + 25;

}
</script>
</head>

<body>
<script language="JavaScript1.2">total1();</script>

<a href='javascript:revisedtotal2();'><img name="mw_1622_sw" src="graphics/mw_1622_sw.jpg" width="75" height="64" border="0"></a>
</body>

Obviously, after I call the revisedtotal2 function I want the value of estimate = 80.


Thanks,

Rich

Hello Rich..
I just modified a bit your HTML page
like this
<a href='javascript:revisedtotal2();alert(estimate)'>
and the alert gave me 80.
Would you please give more details of your problem ?

Good Luck!

Try this instead:

var estimate = 0;

function total1 (){
estimate1 = 55;
estimate2 = estimate1 + 25;
}

and remember that you have to call total1 now.

Sorry again. I'm pretty tired. This should work.

var estimate = 0;

function total1 (){
estimate = 55;
estimate1 = estimate + 25;
alert(estimate1);
}

<html>
<head>

<SCRIPT LANGUAGE="JavaScript">
var estimate = 0;

function total1 ()
{
estimate = 55;
return estimate;
}

function revisedtotal2 ()
{

var tot1 = total1();

estimate = tot1 + 25;

alert(estimate );

}
</script>
</head>

<body onLoad="revisedtotal2();">

</body>
</html>

I'ts not necessary with all the functions.
Code: 
<html>
<head>
<SCRIPT LANGUAGE="JavaScript">
var estimate = 0;

function total1 (){
estimate = 55;
estimate1 = estimate + 25;
alert(estimate1);
}
</script>
</head>
<body onLoad="total1();">
</body>
</html>
That is enought to get it to work.
