I dont see the above "fadeSearch();" on line 80 in the header.tpl. I have this...
<div id="st_search">
<input id="st_search_input" name="posted_data[substring]" type="text" value="{$lng.lbl_product} {$lng.lbl_search}..." onblur="if(this.value=='') this.value='{$lng.lbl_product} {$lng.lbl_search}...';" onfocus="if(this.value=='{$lng.lbl_product} {$lng.lbl_search}...') this.value='';" {if $config.Smart_Template.st_dynamic_search eq "Y"}onkeyup="ajax_showOptions(this,'getProduct',ev ent)" onblur="this.form.submit();" {/if}/>
<input id="st_search_button" type="submit" value="" />
</div>
