Hello,

I have two sets of images (one is white, the other is red) that I need to alternate between in a foreach loop. Is there a way that Velocity can do this, maybe by display one image if the foreach count is odd, and the other image if it is even? Thanks in advance.

   Hi Ashley,

   You should be able to accomplish this by using the $_MathTool.mod() method and $foreach.index. Try something like the following and let me know how it works out:

   #foreach(...)
       #set ($imageColor = "white")
       #if ($_MathTool.mod($foreach.index, 2) == 1)
           #set ($imageColor = "red")
       #end
   
       ## $imageColor will be "white" for even and "red" for odd
   #end
   

   Note: depending on your use case, you may nee to switch the two colors around.

   Please let me know if you have any questions.

   Thanks!
