PHP link needs to be clicked twice to set cookie

I've used a cookie to select which style sheet displays on a page, but have found that I have to click on a link twice before the changes are reflected.

I have the following in the header

PHP Code:

---

setcookie ('select-stylesheet', $chosen, time()+31536000, '/', 'mydomain.com', '0'); 


---

and the following in the body where I want a visitor to be able to select the style sheet they view

HTML Code:

---

<a href="?chosen=default">default sheet</a>

---

Any ideas as to why this might happen?

It sounds like your reading the cookie or looking for what to display before you set the cookie which would give this result. Double check the order of things.

Thanks Reli4nt,

I put the cookie in another page and then redirected back to the page I wanted to refer to it from. That seems to have worked.
