I am new to JavaScript, and one of the reasons why I took learning it to use it on airtable.
Often I need to sum, count and averages of values in a table and hold the value in a block for a while for others to see. This can be done using existing blocks but one each for sum, count and average - which is tedious.
This script makes life easier in such cases. It lets user select the field and table, and even filter conditions before summing, counting and averaging them.
I am planning to add error handling. and warnings to this soon.
