Sending a group of parts via Shortest Queue

I am having troubles sending parts down stream to the queue with the shortest content. What i need to have the program do is look at the item type to see if it changed. If it changes then find out which queue has the smallest content. Then route all parts to that queue until the itemtype changes to reevaluate. What is wrong with my coding?

Much appreciated. Thanks,


treenode item = parnode(1);
treenode current = ownerobject(c);
/**Shortest Queue*/
/** \nSend to the port corresponding to the shortest queue downstream.*/

treenode tempobject;
int curmincontent = 1000000000; // this sets the integer to the largest possible value that an integer can hold.
double curminindex = 0;

double curinitemtype = getitemtype(current);
double lastitemtype = 10000;

if(curinitemtype != lastitemtype)
{
lastitemtype = getitemtype(current);
for(int index = 1; index <= nrop(current); index++)
{
tempobject = outobject(current, index);
if(objectexists(tempobject) && content(tempobject) < curmincontent)
{
curmincontent = content(tempobject);
curminindex = index;
}
}
}
return curminindex ;
