I have a form with a set of questions with radio button answers set up 'Yes', 'No', and 'Don't know'.  I want to count the # of Yes's that the user submitted.

When I use the following code, I always get a count of all my questions, regardless of what I answer.  

$count = 0;
foreach ($form_state['values']['submitted_tree'] as $key => $val) {
  if ($val="Yes") {
    $count++;
  }
}

What am i doing wrong?

There are some good techniques for debugging problems like this.

A good thing to have is develed installed and access to it's dpm() function. It is like var_export() or var_dump() but much better. You can pass dpm and object and then it will show the object on the page in a very readable format. So here's what you should do.

1. Make sure devel is installed.

2. Add this code

dpm($form_state);

3. Look over the output and see where you are making your mistake.

Use a single equal sign as an assignment operator
Use a double equal sign as a comparison operator.

$count = 0;
foreach ($form_state['values']['submitted_tree'] as $key => $val) 
{
    if ($val == "Yes") 
    {
        $count++;
    }
}
