在switch语句中构建添加[]到“”封闭值

Question

我正在使用切换功能编写查询。当我执行查询时，在构建窗口中将值包含在“”中时，Access已在[]中包含了Value语句，并提示我提供一个值。我做错了什么？

关闭构建窗口之前的switch语句是：

OverUnder: Switch([zVAR Days Decision-Open]![Priority Level]="Emergency" 
And [zVAR Days Decision-Open]! [NewDaysToDecision])<=10,”Under”, , [zVAR Days Decision-Open]![Priority Level]="Emergency" 
And [NewDaysToDecision]>10,”Over”, [zVAR Days Decision-Open]![Priority Level]="Level 1" 
And [NewDaysToDecision]<=10,”Under”, [zVAR Days Decision-Open]![Priority Level]="Level 1" 
And [NewDaysToDecision]>10,”Over”, [zVAR Days Decision-Open]![Priority Level]="Level 2" 
And [NewDaysToDecision]<=30,”Under”, [zVAR Days Decision-Open]![Priority Level]="Level 2" 
And [NewDaysToDecision]>30,” Over”, [zVAR Days Decision-Open]![Priority Level]="Level 3" 
And  NewDaysToDecision]<=30,”Under”, [zVAR Days Decision-Open]![Priority Level]="Level 3" 
And [NewDaysToDecision]>30, ”Over”)

我不确定您是否可以使用And语句在switch语句中包含多个条件。这是问题吗？
