二百万 means 'two million' (2,000,000). Note that the pinyin in the source is given as 'èr bǎi', which actually means 'two hundred' (200); the correct pinyin should be 'èr bǎi wàn'. The POS is listed as 'm' (measure word), but 二百万 is a numeral, not a classifier. In usage, it functions as a number that can modify classifiers (e.g., 二百万块钱 'two million dollars') or stand alone as a noun (e.g., 二百万人口 'two million population').
