    Razor If conditional super quick syntax check

    Can someone quickly tell me if my syntax is correct for these conditions in my If statement in Razor?

    var item = (an incremental number);
    var rows = (an incremental number);
    var numInRow = (guess what, an incremental number!);

    if (item % numInRow == 0 && rows == 1) {
   }

    I've checked it with just rows == 1 and that works.
    So its really the item % numInRow == 0 part thats causing the error. (Checking to see if item is a multiple of numInRow).

    Thanks!

    Assuming item, numInRow and rows are  all integers then your syntax is fine. What error are you getting?

    int item =(an incremental number);
    int rows =(an incremental number);
    int numberInRow =(guess what, an incremental number!);

    if(item % numInRow ==0&& rows ==1){
       }

    I am sure that % is something diffrent. What does int test = item % numInRow; give you?
    You do not need to use var i dont think you the type you know will be returned.

    Sorry for delayed reply.  I discovered another way of acheiving what I needed. However, I think it's now irrelevent to this issue! But thank you for your help. I now make sure I'm declaring the type instead of just using var.

    A fun, but apparently well-hidden and non-documented alternative, is to use the InGroupsOf method which can make your code a little easier to read and write. Helpful-looking blog post here in lieu of any official documentation : http://www.simonantony.net/knowledge-base/articles/grouping-nodes-in-umbraco-razor/

    Good luck!
