Can a variable be used as a Macro parameter?

Hi cstone  yes, variable can be used as a macro parameter. Can you please explain what's your requirement. Might be that can be achieved in a easier way.

Hey VikasB, thanks for the reply. The example code I added results in errors. What is the correct syntax for passing in a variable as parameter to a macro?

Here is what I am trying to achieve:

• I am creating a listing of our Boards for the CategoryPage, in the form of "tiles"
• The tiles are arranged in rows of 3, depending on how many Boards are present in a given Category, the final row may have 1 tile, 2 tiles, or 3 titles (if the total count is divisible by 3)
• When there are less than 3 tiles in the final row, I need to add a "shim", so the final tile is the same width as the rest of the tiles.

I plan to achieve this by getting a count of the boards and calculating the remainder when divided by 3:

<#assign boardCount= rest("categories/id/{coreNode.title}/boards/count?restapi.response_style=view").value/>

<#macro repeat count>
  <#list 1..count as x>
    <#nested>
  </#list>
</#macro>

 <@repeat count={boardCount % 3} >
   <li class="detail-tile-shim"></li>
 </@repeat>

If I hard code the count to be something like "2" it works just fine but I keep getting errors when adding a variable as the value of "count" in that macro. 

Thanks cike! This did the trick for me. Here was my final solution, in case this post helps out someone else:

<#assign boardCount= rest("categories/id/sales/boards/count?restapi.response_style=view").value?number/> // apparently this value is a string
<#assign shimCount = 3 - (boardCount % 3) />

<#macro repeat count>
  <#if count != 3>
    <#list 1..count as x>
      <#nested>
    </#list>
  </#if>
</#macro>

<@repeat count=shimCount >
  <li class="detail-tile-shim"></li>
</@repeat>
