如何从CSV导入并将包含的数字加在一起？

我在读取CSV文件时遇到问题，然后将包含的数字相加。
main.au3
$billsRawData1 = FileReadLine(@AppDataDir & "\testDir\test.csv", 2)
$billsArray1 = StringSplit($billsRawData1, ",")
$billsRawData2 = FileReadLine(@AppDataDir & "\testDir\test.csv", 3)
$billsArray2 = StringSplit($billsRawData2, ",")
$billsRawData3 = FileReadLine(@AppDataDir & "\testDir\test.csv", 4)
$billsArray3 = StringSplit($billsRawData3, ",")
$billsRawData4 = FileReadLine(@AppDataDir & "\testDir\test.csv", 5)
$billsArray4 = StringSplit($billsRawData4, ",")
$billsRawData5 = FileReadLine(@AppDataDir & "\testDir\test.csv", 6)
$billsArray5 = StringSplit($billsRawData5, ",")
$billsRawData6 = FileReadLine(@AppDataDir & "\testDir\test.csv", 7)
$billsArray6 = StringSplit($billsRawData6, ",")
$billsRawData7 = FileReadLine(@AppDataDir & "\testDir\test.csv", 8)
$billsArray7 = StringSplit($billsRawData7, ",")
$billsRawData8 = FileReadLine(@AppDataDir & "\testDir\test.csv", 9)
$billsArray8 = StringSplit($billsRawData8, ",")
$billsRawData9 = FileReadLine(@AppDataDir & "\testDir\test.csv", 10)
$billsArray9 = StringSplit($billsRawData9, ",")
$billsRawData10 = FileReadLine(@AppDataDir & "\testDir\test.csv", 11)
$billsArray10 = StringSplit($billsRawData10, ",")
$billsRawData11 = FileReadLine(@AppDataDir & "\testDir\test.csv", 12)
$billsArray11 = StringSplit($billsRawData11, ",")
$billsRawData12 = FileReadLine(@AppDataDir & "\testDir\test.csv", 13)
$billsArray12 = StringSplit($billsRawData12, ",")
$billsRawData13 = FileReadLine(@AppDataDir & "\testDir\test.csv", 14)
$billsArray13 = StringSplit($billsRawData13, ",")
$billsRawData14 = FileReadLine(@AppDataDir & "\testDir\test.csv", 15)
$billsArray14 = StringSplit($billsRawData14, ",")
$billsRawData15 = FileReadLine(@AppDataDir & "\testDir\test.csv", 16)
$billsArray15 = StringSplit($billsRawData15, ",")
$billsRawData16 = FileReadLine(@AppDataDir & "\testDir\test.csv", 17)
$billsArray16 = StringSplit($billsRawData16, ",")
$billsRawData17 = FileReadLine(@AppDataDir & "\testDir\test.csv", 18)
$billsArray17 = StringSplit($billsRawData17, ",")
$billsRawData18 = FileReadLine(@AppDataDir & "\testDir\test.csv", 19)
$billsArray18 = StringSplit($billsRawData18, ",")
$billsRawData19 = FileReadLine(@AppDataDir & "\testDir\test.csv", 20)
$billsArray19 = StringSplit($billsRawData19, ",")
$billsRawData20 = FileReadLine(@AppDataDir & "\testDir\test.csv", 21)
$billsArray20 = StringSplit($billsRawData20, ",")
$total = $billsArray1[3] + $billsArray2[3]; + $billsArray3[3] + $billsArray4[3] + $billsArray5[3] + $billsArray6[3] + $billsArray7[3] + $billsArray8[3] + $billsArray9[3] + $billsArray10[3] + $billsArray11[3] + $billsArray12[3] + $billsArray13[3] + $billsArray14[3] + $billsArray15[3]; + $billsArray16[3] + $billsArray17[3] + $billsArray18[3] + $billsArray19[3] + $billsArray20[3]
MsgBox(0, "", $total)test.csv

10/18/2015,Rent,$750 ,Monthlytest.csv包含可变数量的行。我尝试将第三列中的值相加。我将每一行读入一个变量，并将其拆分为一个数组($billsArray1[3]返回$40)。然后我将这些变量加在一起，但对于$total，它返回0。
1)为什么$total返回的是0而不是total？
2)如何创建一个循环来分配变量(这样我就不需要为每一行创建新的变量，因为我不知道会有多少行)？注意*它总是跳过第一行，所以它从第2行开始。
3)如何创建另一个循环，将第三列的数据相加在一起？
