This is a really, really simple "life-hack" of mine after failed past
attemps to solve this
​ issue​
:
Option
​1​
: Write an if(foreseen error){empty} so if _that_ happens, the code just
ignores it.
​​Option 2: Try to run same code for the different initial values in
different windows, so if one stops, another one keeps running.​
I am interested in finding a real solution
​ (like the one proposed above by Mr. Newmiller)​
, so I am looking forward to some more expert's say.

Best regards.
