It's difficult to tell without looking at the code in the 'header.php' file. Could you show us?

Try changing:

if ($section == "shirt")

to

if ($section == "shirts")

Have you initialised the section variable, after title you need to initiate the section variable. You need to initialize the section as $section = "shirt"; right after the title tag on the shirts page and same on the other pages as well

Sorry Friends! I've done the changes and continue the same trouble <?php $titleName = "Contacto"; $section = "contact"; include('inc/header.php'); ?>

and I've made the change instead of "shirt" for "shirts"

Thanks for your help!

Hmmm, ok the only thing that makes sense is, you are inside the double quotes and then again using the double quotes... Therefore PHP is confused even the HTML for it matters. let me show you

<li class="shirts <?php if ($section == "shirt") { echo "on"; } ?>"><a href="shirts.php">Shirts</a></li>

// <li class="shirts on`"><a href="shirts.php">Shirts</a></li>  .... This is what you need right, Now then
// If you look at your code the class bit where you say ;

<li class="shirts <?php if ($section == "shirt") { echo "on"; } ?>">
// You can see that your shirt variable is wrapped in double quotes. as soon as the double quotes start
// thats the end for the php parsing engine.. hence, change your code as below

<li class="shirts <?php if ($section == 'shirt') { echo 'on'; } ?>">

// Make sure that whenever there is a html double quote you declare your php variables in single
// quotes that the easy way. alternatively you can do as follow

<li class="shirts <?php if ($section == \"shirt\") { echo  \"on\"; } ?>">

//In the above method you are escaping the double quotes

Hope that helps. let me know if it works. cheers
