Since you move the items in process flow, you could easily add activities that change a label value on the queue each time an item is moved into the tote or a tote leaves the queue. This label value can then be displayed by the text object.

Alternatively you can read the number of subnodes of the tote directly in the "Text Display" code.

// Base text
string text = "tote content (code): ";

// Is there a tote in the queue?
Object Queue = Model.find("Queue5");
if(Queue.subnodes.length > 0)
{
    // Add the tote content to the text
    text += string.fromNum(Queue.first.subnodes.length, 0);
}
else
{
    // Add a 0
    text += "0";
}

setnodestr(textnode,text);
return 1;

由於您在流程中移動項目，因此您可以輕鬆地添加活動，每次將項目移入手提袋或手提袋離開隊列時更改隊列上的標籤值。然後，該標籤值可以由文本對象顯示。

或者，您可以直接在“文本顯示”代碼中讀取手提袋的子節點數。
