The challenge wants you to do a for loop that prints the numbers 1 - 100 (including 100)

So for the time being, remove your foreach loop, use print rather than echo, and you might want to add 1 to your for loops terminating condition.

you're printing the wrong outcomes, here is the answer;

```for(\$i = 1; \$i <= 100; \$i++){
print \$i ;
if(isset(\$facts[\$i])){
print \$facts[\$i];
}

}
```
