Hi!
I have followed the previous threads and tried some of the suggestions,
but still could not get my code to run. When I select a button and hit
the "Pick A Color" button, nothing happens. I've included the code for
the html form and the .php file. The book I've been reading suggests
using If/else statements. I saw that some else had used switch
statements. I did try using a switch statement, but it didn't work. The
code below uses the if/else statements. I was also not sure if I should
put the $_POST statement in the if/else since I had used "extract
"$_POST" earlier.
Any help is appreciated!
