variables

[Namal]

There are 3 variables in my Javascript document.Those are:value1, value2, value3.I created a function call mytestfuncion and I included following:function mytestfunction(){value1=10;value2=20;value3=value1+value2;}my expected result is value3= 30. but I received result is: 1020Then pls explain how can get my expected result.

try this

function mytestfunction(){var value1=10;var value2=20;var value3=value1+value2;}

if that doesn't work do this

function mytestfunction(){var value1 = 10;var value2 = 20;var value3 = parseInt(value1) + parseInt(value2);}
