Powerbi 将开关用作嵌套的comaprison时发生Dax错误

嗨，我正试图得到一个基于两个度量值的最后一栏，我使用的是Power BI，但我在这方面是新手。这是公式。我收到一个错误“函数开关不支持将true/false类型的值与text类型的值进行比较”

开关(
和（（‘Table’[ar]*100）=-100，（‘Table’[ar]*100）=-5，（‘Table’[br]*100）=-100，（‘Table’[br]*100）=-5，（‘Table’[ar]*100）=-100，（‘Table’[br]*100）=-100，（‘Table’[br]*100）您得到了那个错误，因为您在
和
函数中有一些包含文本的括号放错了。例如，，（‘Table’[br]*100=-100）&（‘Table’[ar]*100=-5）&（‘Table’[br]*100=-100）&（‘Table’[br]*100=-5）&（‘Table’[ar]*100=-100）&（‘Table’[br]*100=-5）&（‘Table’[br]*100=-100）&（‘Table’[br]*100）&（‘Table’[br]*100）&&
