So, I have a table full of variables that are defined by a datastore. I need to cycle through all the variables and check if they are true. Lets say that 4 of the variables are true, then the script would set the variable Count to 4, or if 7 of the variables are true Count would equal 7. How would I do this?

How do you make a count of the number of variables in a table that are true?

We can use a pairs iterator to enumerate through a table. Evaluate for a True attribute, and increment a count. If we embody this within a function, we can supply any array and retrieve a result:
local ArbitraryTable = {true,false,true,true,false}
local function GetTrueAttributes(Table)
local TrueBools = 0
for _,Boolean in pairs(Table) do
if (Boolean == true) then
TrueBools = (TrueBools + 1)
end
end
return TrueBools
end
local TotalTrue = GetTrueAttributes(ArbitraryTable)
print(TotalTrue) --// 3
