wp_enqueue_script not working

Hi

I’m using the wp_enqueue_script method to add scripts to a theme.

wp_enqueue_script( 'farbtasticJS', '(..)farbtastic.js');

when I look at the postProcessed source I can see the scripts correctly included in the head section, but they are completely ignored by the browser.

If I echo them, they are also correctly included in the head section, but now they are perfectly interpreted by the browser!

echo("<script type='text/javascript' src='(..)farbtastic.js'></script>");

weird!

I want to code this the proper way, and I don’t want to hard-code them by echoing the code.

Can someone please help me to understand what might be wrong?

Thanks
