This should be easy, but, I haven't been able to find an example anywhere.

I need to display {example\_matrix\_a} and {example\_matrix\_b} (both of which contain columns with the same names) via a Stash embed. I've tried the following, but, the Matrix fields aren't parsing. What step am I missing?

**templates/default\_site/example.group/layout\_example.html:** 

```
{embed="wrappers/_interior"}

{exp:channel:entries limit="1"}
    {exp:stash:set name='title'}{title}{/exp:stash:set}
    {exp:stash:set name='maincontent'}
      {stash:embed:matrix_markup
        stash:matrix_field = "{example_matrix_a}"
        process="start"
      }
      {stash:embed:matrix_markup
        stash:matrix_field = "{example_matrix_b}"
        process="start"
      }

  {/exp:stash:set}
{/exp:channel:entries}

```

**stash\_templates/matrix\_markup.html**

```
{stash:matrix_field} 
   {matrix_col_1} - {matrix_col_2}<br>
{/stash:matrix_field} 

```
