[TYPO3-mvc] Limit displaying pages

[Dimanche]

Hi,

I have problem with this function:

(*) $this->settings['limit'];

I would like to display my pages by limiting in flexform, but I could 
not get the value from backend entry by using (*).

Here is my flex form:

<limit>
   <TCEforms>
      <label>Max. number of members to display at once</label>
         <config>
           <type>input</type>
           <size>2</size>
	  <eval>int</eval>
	  <default>5</default>
         </config>
    </TCEforms>
</limit>

The question is that, how can I get the value from flexform when admin
enter the value?

Dimanche
