Hey Kevin - Unfortunately that won't do it. There is no built-in way to display the results of multiple donation pages in one progress bar. However, it is possible with some custom coding using Liquid and HTML.

It sounds like you want to measure the number of total donors on your site rather than just the number of donors on one page. If so, the Liquid variable {{ settings.donors_count }} will be helpful here. Your donation page's Template probably has a snippet of code in it that looks like this:

<div class="clearfix">
{% if page.donations_count < 2 %}
<div class="bar-text bar-text-null">JUST STARTED</div>
{% else %}
<div class="bar-text">{{ page.donations_count }} donors</div>
{% endif %}
<div class="bar-goal">{{ page.donation.donor_goal }} donors</div>
<div class="progress" style="width: {{ thermo_width }}%;">
<div class="bar bar-success" style="width: {{ page.donation.percent_of_donor_goal | times:100 }}%;">
</div>
</div>
</div>

However, you can change it to this:

<div class="clearfix">
{% if page.donations_count < 2 %}
<div class="bar-text bar-text-null">JUST STARTED</div>
{% else %}
<div class="bar-text">{{ settings.donors_count }} donors</div>
{% endif %}
<div class="bar-goal">{{ page.donation.donor_goal }} donors</div>
<div class="progress" style="width: {{ thermo_width }}%;">

{% capture bar_width %}{{ settings.donors_count | divided_by: page.donation.donor_goal }}{% endcapture %}
<div class="bar bar-success" style="width: {{ bar_width | times:100 }}%;">
</div>
</div>
</div>
