Counting the number of variable columns that have non-zero values

[#1]

I have a table of formulations.  The amount of each of 60 possible ingredients are listed in columns.  Most of the formulations contain only 5-10 ingredients with the ingredient amount of all other columns being zero.

I would like to create a formulation column (without scripting) to count the number of non-zero ingredients.

The way I was thinking to do this is to sum conditional statements for each ingredient.  This shows the first 4 ingredients:

Is there a quicker/easier way to do this without having to create a string of 60 if statements?

You can shorten the code up to

sum( :T400>0,:T402>0,:T404>0,:T405>0)
