Extended Nested if statements in Excel: error in processing

I want to use nested if statements as a method of filtering data in Excel, and have written a series of nested if statements, however, the code won't compile in the Excel formula line and comes up with an error saying "the formula you typed contains an error", but I don't know where the error could be.

IF(FILTERS!$V$7= "", IF (FILTERS!$AC$7 = "", IF (SHEET1!$T2 = FILTERS!$B$17, IF (SHEET1!$U2 = FILTERS!$C$17, IF (SHEET1!$V2 = FILTERS!$D$17, IF (SHEET1!$W2 = FILTERS!$E$17, IF (SHEET1!$X2= FILTERS!$F$17, A2, "") ,""), "" ) ,""), ""),IF (SHEET1!$M2 = FILTERS!$AC$7, IF (SHEET1!$T2 = FILTERS!$B$17, IF (SHEET1!$U2 = FILTERS!$C$17, IF (SHEET1!$V2 = FILTERS!$D$17, IF (SHEET1!$W2 = FILTERS!$E$17, IF (SHEET1!$X2 = FILTERS!$F$17, A2, ""), ""), "") , "") , ""), “”)), IF(SHEET1!$H2 = FILTERS!$V$7, IF (FILTERS!$AC$7 = "", IF (SHEET1!$T2 = FILTERS!$B$17, IF (SHEET1!$U2 = FILTERS!$C$17, IF (SHEET1!$V2 = FILTERS!$D$17, IF (SHEET1!$W2 = FILTERS!$E$17, IF (SHEET1!$X2= FILTERS!$F$17, A2, "") ,""), "" ) ,""), ""), ""),IF (SHEET1!$M2 = FILTERS!$AC$7, IF (SHEET1!$T2 = FILTERS!$B$17, IF (SHEET1!$U2 = FILTERS!$C$17, IF (SHEET1!$V2 = FILTERS!$D$17, IF (SHEET1!$W2 = FILTERS!$E$17, IF (SHEET1!$X2 = FILTERS!$F$17, A2, ""), ""), "") , "") , ""), ""), ""))

Thank you in advance!!
