Having issues with adding php to Wordpress function.php?

[Acknowledged74]

Hi

I have a Wordpress setup and theme running nicely. I want to add a shop and Woocommerce has been recommended as the right way to go, so I've installed that nice and easy, but it doesn't work with my theme.

I found this,

I am trying to implement the hook. But I'm struggling as I find the instructions unclear.

I'm sure this doesn't need any past knowledge of Woocommerce just of php.

I've added the following to line 31 of the function.php file

add_action('woocommerce_before_main_content', 'my_theme_wrapper_start', 10);
add_action('woocommerce_after_main_content', 'my_theme_wrapper_end', 10);

function my_theme_wrapper_start() {
echo '<section id="maincontent">';
}

function my_theme_wrapper_end() {
echo '</section>';
}

which to be honest is just area of the function.php with a gap. I've copied the function.php content into a Word doc linked to below.

Any help on this would be great, Woo won't help until you have bought additional extensions, but if I can't get it to work, why should I?
