2.4 Variable: What's wrong?

Hi,

i’m stuck on exercice 2.4 here is my code

    <body>
    <p><?php $myFirstVariable = 10-10; echo $myFirstVariable; ?></p>
</body>

and I always have the same result:

Oops, try again. Did you remember to set $myFirstVariable to 0? Don’t forget the semicolon!

What am I missing there?

thanks

I found I needed to use Amal Muralis trick -

If your code is correct and you don’t get any output: Hit Ctrl + F5.

As the web page just did nothing after clicking submit before that!

Your code is this:

<p><?php $myFirstVariable = 10-10; echo $myFirstVariable; ?></p>

I passed with this:

<p><?php $myFirstVariable = 0; ?></p>

Hope this works!

Don’t forget to print it exactly, as in myFirstVariable instead of myfirstvariable in all lower case, took me while to work that one out !

2.4 and 2.5 are broken and won’t work if you follow the instructions. I’ll learn PHP elsewhere.
