For that, I store all variables in two arrays (one for used, one for definition) and at the end I evaluate if each variable in in the used array are present in the defined array. The crossing link, distribution and security about not defined variables work well. The problem is on the link in the "Matrix" table, all link to the same.
You can find the code below :
