I believe the answer is:
target
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fixed goal</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for target that I've seen before include "Object to be attained by archers (or fund raisers?)" , "Object to be aimed at" , "Objective, mark" , "A result to aim at" , "Goal to be aimed for" .)
