Happy to provide extra info.
Second problem is this data isn't being added properly.
{% set offenseTotal = 0 %}
<div class="mastery_ Offense">
{% for i in range(511, 571, 10) %}
{% set currentMax = i + 4 %}
{% for j in range(i, currentMax) %}
{% if j in page['offensive'] %}
<div class="masterblock {{ "maxrank"
if page['offensive'][j] ==
denominators[j] }}">
<div class="mastery_icon">
<div data="{{ j }}"
id="tra-target-{{ j }}"
class="masterysprite gtooltip
m{{ j }}" ></div>
<div class="master_rank">{{
page['offensive'][j] }}/{{
denominators[j] }}</div>
{# This was a test case and
isn't even working {% set
offenseTotal = (offenseTotal +
1) %} #}
{% set offenseTotal =
offenseTotal +
page['offensive'][j] %}
</div>
</div>
{% elif j not in [521, 534, 554, 561, 563,
564] %}
<div class="masterblock norank">
<div class="mastery_icon">
<div class="masterysprite m{{
j }}" ></div>
<div class="master_rank">0/{{
denominators[j] }}</div>
</div>
</div>
{% else %}
<div class="masterblock"></div>
{% endif %}
{% endfor %}
{% endfor %}
<div class="masterytitle">
Offense : {{ offenseTotal }}
</div>
</div>
Once again happy to provide extra info. Thanks for any guidance!
