this will be hell
ideally we would be able to iterate over all the magazine name parameters, but I highly doubt mediawiki is that smart - Andlabs 16:15, 2 March 2012 (CST)

or not, but this still isn't optimal - we'd need to use prefixes for the score parameters - Andlabs 16:19, 2 March 2012 (CST)

Not sure how you're doing things here, but you should be able to calculate totalReviews like so: {{#if {{{ug|}}} | 1 | 0 }}+{{#if {{{vgce|}}} | 1 | 0}}+etc. - Hivebrain 22:17, 2 March 2012 (CST)
