I have a macro that adds a 2 new tables to a sheet, a new table for each day to the right of the previous day tables (the 2 daily tables are vertically stacked). There are total rows in the new tables, and I need to insert a formula that calculates the difference between one of the total columns for the new day and the previous day's total. I recorded a macro that I planned to edit to include variable references rather than fixed references. I'm now stuck at how to address the second part of the formula below:

The "Cases051920" table name is the variable. Each day, it will be a different date. Today's is "Cases052020", and tomorrow's new table will need to reference this table - and so on. How do I turn this into a variable so the macro can insert the formula so that it references the correct prior day's table???

This is the recorded bit of code that I'm trying to adapt:
