The thing to the left of the ? *is* the if--you don't need the keyword "if" at that point.

<a href="<?php (the_title() == 'Hormone Therapy') ? echo 'hormones' : echo '#'; ?>" title="<?php the_title(); ?>">

Try this one
<a href="<?php $title=(the_title() == 'Hormone Therapy') ?  'hormones' : '#'; ?>" title="<?php echo $title; ?>">

still not working, here is the results of that:

<a class="nivo-imageLink" title="Nutrition Counseling" href="Nutrition Counseling#" style="display: block;">
<a class="nivo-imageLink" title="Hormone Therapy" href="Hormone Therapy#" style="display: none;">
<a class="nivo-imageLink" title="Botox" href="Botox#" style="display: none;">

it should be:

<a class="nivo-imageLink" title="Nutrition Counseling" href="#" style="display: block;">
<a class="nivo-imageLink" title="Hormone Therapy" href="hormones" style="display: none;">
<a class="nivo-imageLink" title="Botox" href="#" style="display: none;">

Are you sure this code is the one running? The current result you mention isn't showing the anchor's attributes in the order you have defined them. In other words, your code is showing that the href should come before the title, but your example output shows the reverse.

What did your function return? it must work I have tested using a test function:
<?php
function the_title(){
	$title='';// Change value of Function To Hormone Therapy next time and hover on link you will see the title changed
	return $title;
}
?>

Open in new window

<a class="nivo-imageLink" href="<?php $title=(the_title() == 'Hormone Therapy') ?  'hormones' : '#'; ?>" title="<?php echo $title; ?>" style="display: block;">Nutrition Counseling</a>
<a class="nivo-imageLink" href="<?php $title=(the_title() == 'Hormone Therapy') ?  'hormones' : '#'; ?>" title="<?php echo $title; ?>" style="display: block;">Hormone Therapy</a>
<a class="nivo-imageLink" href="<?php $title=(the_title() == 'Hormone Therapy') ?  'hormones' : '#'; ?>" title="<?php echo $title; ?>" style="display: block;">Botox</a>

nothing is going to work guys, the js file changes everything.

I just hard coded the link and from the link it will redirect to the appropriate page.

I'm giving you all credit for answers.
