The query includes a pivoted dimension, **Products Category** , which has the values `Swimwear` and `Coats`. To compute the total number of orders made in each season across all categories, create a **Total Orders Count** table calculation.\n\nThe **Total Orders Count** table calculation adds the value of the first pivot column to the value of the second pivot column. The formula is: \n\n pivot_index(${orders.count}, 1) + pivot_index(${orders.count}, 2)\n\nThings to know\n--------------\n\n`pivot_index` cannot be used in a [custom filter](/looker/docs/filtering-and-limiting#custom-filters)."]]
