<form action=....>
---
<input type=checkbox name=colour value=red>Red
<input type=checkbox name=colour value=yellow>Yellow
<input type=checkbox name=colour value=black>Black
<input type=checkbox name=colour value=white>White
---
</form>

Anytime I submit the form, only one value gets sent even after checking all the boxes. I tried using Perl/CGI for the target script and it worked fine. What am I doing wrong using php as the target script?
