actual error seems hidden in traceback during TemplateSyntaxError #763
Description
it seems like the actual error from a template designer perspective is hidden way up in the traceback:
File "./myorg/hss/football_game/pagebuilder/score_by_quarter.j2", line 145, in template
{%- elif loop.previtem and loop.previtem.away_total > loop.previtem.home_total and period.away_total > period.home_total and period.away_total-period.home_total > loop.previtem.away_total-loop.previtem.home_total > -%}
is there a way to make the error a little nicer at the bottom of the traceback?
