FusionTables更新查詢不起作用

我正在用下拉菜單構建FusionTables地圖。我希望地圖上的標記根據用戶在下拉菜單中的選擇進行更改。每個菜單選項都對應於Fusion Table中「可能性」列的三個選項。我使用這些鏈接作爲參考：FusionTables更新查詢不起作用

http://sportstleo12.appspot.com/和https://developers.google.com/fusiontables/docs/samples/change_query

我已經複製的代碼，到目前爲止，我可以得到所有的選項來顯示，但它不會根據用戶的結果進行過濾選擇。我相信這很簡單。有任何想法嗎？

這裏是迄今爲止代碼：

請發表你的答案爲_answer_不作爲問題的一部分。如果你描述了問題是什麼以及解決了什麼問題，那也是有用的。 – geocodezip

我不知道什麼是錯的我之前發佈的代碼。我發現這個鏈接，幫我把它寫不同和solce我的問題：
