Portfolio Category to show on selected page only

Site is Albury Lifestyle Village

The Albury – Wodonga Region page is using page template portfolio 2, & we want only the albury_wodonga portfolio category to show.
The Testimonials page will be using page template portfolio 1, and again we only want the testimonials portfolio category to show.

Part of the code I think I need to edit in both the portfolio 1 & 2 php files is …

‘<?php get_header(); ?>
<div id=”content-full”>
<h1 style=”margin-bottom:15px;”>Page Title</h1>
<div id=”portfolio-sortable”>
<span> ‘1’, ‘filter’ => ”)); // Reset the category filter to show all posts ?>”>Show All</span>
<?php // Create a menu for filtering posts by their portfolio category
$categories= get_categories(‘taxonomy=portfolio_category&title_li=’);
foreach ($categories as $category){ ?>
<span> ‘1’, ‘filter’ => $category->category_nicename));?>” title=”Filter by <?php echo $category->name;?>”>
<?php echo $category->name;?></span>
<?php }?>
</div>’

I’m at a lost what I need to edit & replace with what.
Unfortunately support doesn’t get back to me until some stupid hr in the morn my time & then they only ask for admin access. I have now wasted two days on trying to figure this out.
If anyone could help, it would be greatly appreciated.

Thanks
Simone
