the question Placeholder text is used to give people a hint about what kind of information to enter into an input. For example, <input type="text" placeholder="Email address">.
Add the placeholder text cat photo URL to your input element.
<input type="text" name="catphotourl" placrholder="cat photo URL">
If you click on the help icon which appears when you have failed to submit the correct code three times, it will create a forum post template which will allow you to link your full code and a direct link to the challenge, which will make it easier for people to help you.
I did notice however that you have spelled ‘placeholder’ incorrectly.
