JavaScript Equation Problems

Hi All,

Being a bit of a newbie to Javascript i'm having a few issues trying to get an equation to work on a program I am trying to create.

Based on what the user inputs into a input field I want it to do the following

((userValue/3)*4) - where userValue = whatever is entered into the input field.

I have tried the following code which doesn't appear to return the results I wanted

var in_value1 = document.getElementById('in-value1').value;
document.getElementById('in-result2').innerHTML = (parseInt(in_value1) * parseInt(2.54)) / parseInt(100);

Any help would be appreciated.

Thank you

You want:
(userValue/3)*4

but your code is:
(userValue*2.54)/100

So just change the code.

Additionally, you don't need to use parseInt all over the place. Javascript will convert strings to integers for you.
