Can't find my mistake :(

Hi there, Neven Shtiliyanov! First, and foremost, you are completely overwriting the `\$facts` array with essentially a `null` because `\$i` is not defined at this point. But you don't want to overwrite facts at all.
So start by removing `\$facts = \$i;`
Your `for` loop is starting at 1 and going up to 100 (inclusive). What we want to know is if `\$facts[1]` has a value. It doesn't. But `\$facts[2]` does.
There should be a check inside your for loop on `\$facts[\$i]` to see if it `isset`. If it is set, echo out `\$facts[\$i]`
