I stucked here


Oops, try again. Did you add two table header cells within the row you just created within <thead></thead>? (Table header cells are <th></th>, not <td></td>!)
and i did what he said :frowning:

Please post a link to the exercise you are working on so that I can move your post the right category – or you should be able to do it yourself.

I was able to reproduce the error message by writing TD instead of TH, as instructed, and indicated by the error message.

This is the markup that raised the SCT error:

                    <td>Famous Monster</td>
                    <td>Birth Year</td>     

If your code looks like this, then the problem is simple enough to fix. Change all the td's to th's.
