2.为了进一步继续这个，我还想要只有BS的百分比。引擎。示例：假设在报告中，所有年度数量的总和为100,000。其中，BS是指BS。 100,000个引擎中有10,000个引擎。我知道这是10％，但我不知道要放入该文本框的控制源的代码。

我尝试了这个代码：DSum（[Year Qty Est]，Area_1_Products，[Engine Manufacturer] =" Kohler &安培;我。[引擎制造商]）


我得到的是一个错误说明：查询表达式中的语法错误（缺少运算符）First（[DSum（" [Annual Qty Est] ]"，" Area_1_Products"，" [Engine Manufacturer] =" Kohler"& Me]。[[Engine Manufacturer]）]）''。


那么什么我做错了吗？你能帮忙吗？

Area_1_Products是此报告尝试生成的查询。

和引擎制造商是正确的而不是引擎制造商。

如果你知道引擎制造商将永远是科勒，那么它应该是：

I have a textbox called Engines Manufacturer. This texbox gives me the type of engine that is on the product. I also have a textbox called Annual Qty Est. This textbox give the number of engines that is on that particular product. I have 2 questions.

1. I want to know the code to put in my textbox control source to see only the Annual Qty Est for a particular Engines Manufacturer. Example: In the Engines Manufacturer column in the report I have an engine called "BS". I want to know only the Annual Qty Est for "BS" engines.

2. To further go on this, I also want to the the percentage for only "BS" engines. Example: Lets say that on the report the sum of all Annual Qty Est is 100,000. Out of that, "BS" engines is 10,000 out of that 100,000. I know this is 10%, but I don''t know the code to put into my control source for that textbox.

Can I please get some help on this matter.

I tried this code: DSum("[Annual Qty Est]", "Area_1_Products", "[Engine Manufacturer] = "Kohler" & Me.[Engine Manufacturer])

And all I get is a error stating: Syntax error (missing operator) in query expression "First ([DSum("[Annual Qty Est]", "Area_1_Products", "[Engine Manufacturer] = "Kohler" & Me].[[Engine Manufacturer])])''.

So what am I doing wrong? Can you please help?
The Area_1_Products is the query in which this report is trying to generate.
And Engine Manufacturer is correct instead of Engines Manufacturer.

If you know Engine Manufacturer will always be Kohler, then it should be:
