Looks like you need to change entry.mark to just mark and remove the
<s:property value="%{entry}"/>. Also you probably don't need to pass both
the name and id of the parent object.
<a href="<s:url action='DeleteEntryForm' var="entry" escapeAmp="false">
<s:param name="id" value="%{goalToAchieve.id}" />
<s:param name="mark" value="%{mark}" />
</s:url>
">Remove</a>
