The problem is the linebreak in this part:
target="ej_ejc" class="ec_ejc_thkbx" onClick="javascript:return
EJEJC_lc(this);">
The attribute onClick="javascript:return EJEJC_lc(this);" can't be split into separate lines.
Also, I would recommend adding a linebreak after the <!-- like so:
<!--
function EJEJC_lc(th) { return false; }
...etc.
