Help with WP Project Manager

I am hoping someone can help me to make heads or tails of this. I am wanting to add custom fields to WP project manager (address, number, email). I emailed their support, and was given a very vague description on how to make the changes. Since I am no developer, and wordpress has an amazing community of people who do not mind helping out. Please help. You can visit the URL http://wedevs.com/support/topic/custom-fields-when-adding-a-project/#post-21365
to see my post, and the help I got.

I am suppose to put add_action('cpm_project_form', array($this,'new_project_field'),10,1); into the function_construct ()

and I am suppose to put `function new_project_field($project){
?>
<label><?php _e(‘E-mail’, ‘cpm’); ?></label>
<input type=”text” name=”user_email”>

<?php
}
` inside the cpm.php somewhere.

If I knew the files and placement I am sure I could figure it out, but I do not really understand php too well.

Thanks for helping me out 🙂
