Thank you [RicardoTM] for your explanation.

Understanding a little snippet makes the difference between understanding the whole code or not.
What matters here is that you understand the concept.
Just to add why it didn't work. The syntax #Variable#[#VariableIndex] you used is wrong because it implies a #variable# and a #variableIndex# since in your code there's no #variable# then that part won't be solved, so its result will be literally #variable#1, which is incorrect.
If there was indeed a #variable# for example
Variable=Value
VariableIndex=1
Then #variable#[#VariableIndex] would be equal to the string "Value1"
This could be useful like if you had something like
Meter=SomeMeter
MeterIndex=2
[SomeMeter1]
[SomeMeter2]
Then #Meter#[#MeterIndex] would be equal to the string "SomeMeter2"
