Unable to understand the compilation error here.

I have the following submission in scala for one of the practise questions at http://www.codechef.com/problems/INTEST/ and I keep getting compilation error. I compared it with other submissions and I just have a few lines of difference. But I still get a weird error. Please help.

object Main {
   def main(args: Array[String]) {
      val inputs = readLine.split(" ")
      val n = inputs(0).toInt
      val mod = inputs(1).toInt
      var sum = 0
      for (i <- (1 to n))  {
         var myvar = readInt
         if (myvar % mod == 0) sum += 1
      }
      println(sum)
   }
}

Here is the compilation error. http://www.codechef.com/view/error/2506294/
