Razor If conditional super quick syntax check

Razor
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!
