Hotspot Portal accesible variables

RouterOS General
1

Hi All,
I want to detect in the portal if the checkbox in the Cookie under → IP> Hotspot> Hotspot Server Profile > Login tab is checke or unchecked.
The Trial is working like this:

 
  <p class="info $(if error)alert$(endif)">
               $(if error == "") 
                   $(if trial == 'yes')
                   <br />Free trial available, <a href="$(link-login-only)?dst=$(link-orig-esc)&amp;username=T-$(mac-esc)">click here</a>.
                   $(endif)
                $(endif)
                $(if error)$(error)$(endif)
 </p>

now I’m trying like this:

  
  $(if Cookie == 'no')
  <br>no cookie</br>
$(endif)

Seems that Cookie is not the variable I need, i also tried “cookie” small “c” but no success.
Please anyone help me if there are list of variables we can pull in the hotspot portal, thanks
