I think there are two problems with the drill downs in master_basic_stats.view.lkml, eg: https://github.com/llooker/google_adwords/blob/dev-dillon-morrison-ycx9/master_basic_stats.view.lkml#L337

1. Missing trailing ,'s in all of the if / else logic.
   Eg: campaign.campaign_name{% endif %}master_stats.total_impressions renders to: campaign.campaign_namemaster_stats.total_impressions, which is an invalid field name.

2. The url escaped vis=... logic doesn't work? When I click through, I get a link with vis=undefined.
   Eg: vis=%7B%22type%22%3A%22table%22%2C%22show_view_names%22%false%2C%22show_row_numbers%22%3Atrue%2C%22truncate_column_names%22%3Afalse%2C%22hide_totals%22%3Afalse%2C%22hide_row_totals%22%3Afalse%2C%22table_theme%22%3A%22editable%22%2C%22limit_displayed_rows%22%3Afalse%2C%22enable_conditional_formatting%22%3Afalse%2C%22conditional_formatting_include_totals%22%3Afalse%2C%22conditional_formatting_include_nulls%22%3Afalse%7D
