Seems like trying to use '''expr''' with '''var_final''' causes an error. Any thoughts? - [[User:Hivebrain|Hivebrain]] ([[User talk:Hivebrain|talk]]) 16:22, 1 July 2015 (CDT)
:From the two minutes I've taken to look into this, I think var_final is created at the very last minute, i.e. after all the standard wiki parsing has been done.

:So it's not really a variable at all I guess. I can't... vary. -[[User:Black Squirrel|Black Squirrel]] ([[User talk:Black Squirrel|talk]]) 11:52, 2 July 2015 (CDT)


::I'm thinking the best plan might be to introduce loops: https://www.mediawiki.org/wiki/Extension:Loops

<pre>
{{#vardefine: totalReviews|0}}
{{#vardefine: cumulativeScore|0}}


{{#vardefine: finished|false}}
{{#vardefine: oneLoop|false}}

<!-- while not done  -->
{{#while:| {{#ifeq: {{#var: finished}}|false}} |

    {{#ifeq: {{#var: oneLoop}}|true|
        <!-- if looped once -->
        {{#vardefine: average|{{#expr: {{#var: cumulativeScore}} / ({{#var: totalReviews}} * 100) }} }}
        {{#vardefine: finished|true}} <!-- exit after this loop -->
    | }}   

    <!-- add up scores (this gets done twice) -->
    ...
    {{#vardefine: totalReviews|{{#var: totalReviews}} + 1}}
    {{#vardefine: cumulativeScore|{{#var: cumulativeScore}} + score}}
    ...
    
    {{#vardefine:oneLoop|true}}
}}
</pre>

no idea if the syntax works but yeah.

: Loops looks like a useful extension, but I don't see how it would help here. The problem is, I wanted to combine the score averaging stuff with the collapsible content, but since the average is shown first I needed to use var_final. This didn't work, so it looks like the only option is to put the averaging back where it was originally. - [[User:Hivebrain|Hivebrain]] ([[User talk:Hivebrain|talk]]) 13:53, 2 July 2015 (CDT)

::The idea is that on the first loop, the cumulativeScore and totalReviews variables are added to, and on the second, the averaging occurs. Above what would be the collapsible content.

::it's the only way I can think of getting data that's at the "bottom" to the "top". -[[User:Black Squirrel|Black Squirrel]] ([[User talk:Black Squirrel|talk]]) 14:19, 2 July 2015 (CDT)
