What's the right way to use the value of a variable in a User Macro

[Brainshark Operations]

I"ve got a user macro that has some code like this in it:

#set($containerManagerClass = $content.class.forName('com.atlassian.spring.container.ContainerManager'))
#set($getInstanceMethod = $containerManagerClass.getDeclaredMethod('getInstance',null))
#set($containerManager = $getInstanceMethod.invoke(null,null))
#set($containerContext = $containerManager.containerContext)
#set($loginManager = $containerContext.getComponent('loginManager'))
#set($users = $userAccessor.getUsers())
#set($numUsers = $users.size())

<div class="aui-message closeable">
Total Licenses Being Used: ${numUsers}
</div>

 I know that $users has elements in it, because later on when I loop over it, I can print out each user on the page. I've tried a number of different reasonable looking syntaxes for trying to print out the value of numUsers, but I'm not getting that value on my page.

What's the proper way to reference a variable in my User Macro? 

I've tried the above as well as:
$numUsers
#$numUsers
$!{numUsers} - which was just blank

Hi,

the number of users of the userAccessor.getUsers() does not necessarily reflect the number of consumed licenses. You should count the users of the user groups granted access to Confluence.

Try:

## @param group:title=Group|type=string|required=true|desc=User group|default=confluence-users

#set($containerManagerClass = $content.class.forName('com.atlassian.spring.container.ContainerManager'))
#set($getInstanceMethod = $containerManagerClass.getDeclaredMethod('getInstance',null))
#set($containerManager = $getInstanceMethod.invoke(null,null))
#set($containerContext = $containerManager.containerContext)
#set($loginManager = $containerContext.getComponent('loginManager'))

#set($now=$content.currentDate.time)
#set($group = $userAccessor.getGroup($paramgroup))
#if($group)
#set($usernames = $userAccessor.getMemberNames($group))
#end
#set($totalactiveusers = 0)
<table class="confluenceTable" width="660px">
<tr>
<th class="confluenceTh">Name</th>
<th class="confluenceTh">Last login</th> 
<th class="confluenceTh" style="text-align:center;">Days/Status</th>
</tr>
#foreach($username in $usernames)
#set($t3="9999")
#set($user = $userAccessor.getUser($username))
<tr>
<td class="confluenceTd">#usernameLink($user.name)</td>
<td class="confluenceTd" style="text-align:center;">$action.dateFormatter.formatGivenString('yyyy-MM-dd HH:mm',$loginManager.getLoginInfo($user).lastSuccessfulLoginDate)</td>
#if($loginManager.getLoginInfo($user).lastSuccessfulLoginDate)
#set($t3= $now - $loginManager.getLoginInfo($user).lastSuccessfulLoginDate.time)
#set($t3= $t3/1000/24/60/60)
#end
<td class="confluenceTd" style="text-align:center;">
#if($userAccessor.isDeactivated($user))
<ac:macro ac:name="status">
<ac:parameter ac:name="colour">Red</ac:parameter>
<ac:parameter ac:name="title">Locked</ac:parameter>
</ac:macro>
#else
#set($totalactiveusers = $totalactiveusers + 1)
#if($t3 < 7) 
<ac:macro ac:name="status">
<ac:parameter ac:name="colour">Green</ac:parameter>
<ac:parameter ac:name="title">$t3</ac:parameter>
</ac:macro>
#elseif($t3 < 31) 
<ac:macro ac:name="status">
<ac:parameter ac:name="colour">Blue</ac:parameter>
<ac:parameter ac:name="title">$t3</ac:parameter>
</ac:macro>
#elseif($t3 < 180) 
<ac:macro ac:name="status">
<ac:parameter ac:name="colour">Yellow</ac:parameter>
<ac:parameter ac:name="title">$t3</ac:parameter>
</ac:macro>
#else 
<ac:macro ac:name="status">
<ac:parameter ac:name="colour">Red</ac:parameter>
<ac:parameter ac:name="title">$t3</ac:parameter>
</ac:macro>
#end
#end
</td>
</tr>
#end
</table>
<p>Active users in group <b>$paramgroup</b>: $totalactiveusers</p>

Best
