I use Selenium IDE. I love it. Recently we decided to move to Katalon for Chrome to support what the Business needs.
I was happy that my Selenium scripts can be used but I was stumped by the fact that arrays through a loop would not work.
It messed me about for a day and a half until I realise that one needs to first create an extra storeEval to store the array element before echoing it out.
Now my array works.
I have attached the script commands, red = does not work and green = it works, and most of the output of the loop.
