Javascript issue

Hello - I have a button that has a (a href) and a (onclick) on it which control two different java functions.

When you press the button only one of the functions is activated.

I check each function on their own and they work fine… I just get snagged when I combined them onto one button.

Please help if you can!!

Here is the code;

<[COLOR=Red]a href[/COLOR]="javascript:change_image(‘detail’,‘images/Sunriver_2.jpg’); "[COLOR=Red]onclick[/COLOR]=“togLayer(‘thumbnails_featured2’);return false;”><img src=“images/sunriver_2.gif”/>
</a>
