Javascript: for-loop not working

Question

I have this code right here.. where the variable num is the dimension of a n by n square table. The objective is to enter a number and create a table with the number as the dimension. I got this code but it doesn't go through the 2 layers of for-loops. After the code execution, the string *change_text* just becomes: `

` ``` change_text = ""; for (var i; i"; for (var j; j asdf "; //code for blue cells } change_text = change_text + ""; } change_text = change_text+ "

" ```

Accepted Answer

You need to initialize your iterators:

```
for(var i = 0; i < num; i++)
```
