Setting variable in layout not passing value from child template

[GitTworn]

In the global (most outer) layout I would like to get some member variables and pass them on the a template that uses.

_global_layout

{if logged_in}
    {exp:stash:set scope='user' parse_tags='yes' save="yes"}
        {exp:visitor:details}
            {stash:st_logged_in_member_gender}{visitor:member_gender}{/stash:st_logged_in_member_gender}
            {stash:st_logged_in_member_first_name}{visitor:member_firstname}{/stash:st_logged_in_member_first_name}
            {stash:st_logged_in_member_last_name}{visitor:member_lastname}{/stash:st_logged_in_member_last_name}
            {stash:st_logged_in_member_email}{visitor:username}{/stash:st_logged_in_member_email}
        {/exp:visitor:details}
    {/exp:stash:set}
{/if}

In a child template I want to use them.

_newsletter_form
<input type="text" class="form-control" id="first_name" name="first_name" placeholder="First name" value="{if {exp:stash:not_empty name='st_logged_in_member_first_name'}}{exp:stash:get name='st_logged_in_member_first_name'}{/if}">
OR
<input id='radio-mr' type="radio" name="gender" value="male" {if '{stash:embed:st_logged_in_member_gender}' == 'male'}checked="checked"{/if}> <--- does not work either

This is not working.

When I use {stash:embed:st_logged_in_member_first_name} it does give me the correct value, however I can't seem to get it to work with a conditional.
