SSRS multi value array is returning only highest /last index value for all column of different arrays instead conditions are applied

Question

=SWITCH(
Array.IndexOf(Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Team.Value,"Dataset1"), ","),","), "Some xyz Value") = "-1","NA",
Array.IndexOf(Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Team.Value,"Dataset1"), ","),","), "Some xyz Value") = "0", Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Created.Value,"Dataset1"), ","),",").GetValue(0)),
Array.IndexOf(Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Team.Value,"Dataset1"), ","),","), "Some xyz Value") = "1",
Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Created.Value,"Dataset1"), ","),",").GetValue(1),
Array.IndexOf(Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Team.Value,"Dataset1"), ","),","), "Some xyz Value") = "2",
Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Created.Value,"Dataset1"), ","),",").GetValue(2)
)

Below is my logic in this switch condition I am trying to implement below logic but each time only highest index value is returning for different arrays.

   Array used for below 1 point = []

    Array used for below 2 point  = ["1st value"]

   Array used for below  3 point  = ["1st value" , "2nd value"]

   Array used for below  4 point  = ["1st value" , "2nd value" , "3rd value"]

   1. If some value is not found in array then array index of is returning -1 and it should print NA as per logic in switch.

   2. If some value is found on array index 0 then array index of is returning 0 and it should fetch created date of index 0 (1st value)

   3. If some value is found on array index 1 then array index of is returning 1 and it should fetch created date on index 1 (2nd value)

   4.If some value is found on array index 1 then array index of is returning 2 and it should fetch created date on index 2 (3rd value)

   But currently it is returning 3rd value only for point 4 where array length is 3 but for others it is returning error where array length is 2, 1 or 0  because it is checking length 3 there as well don't know why Ideally it should work based on array index condition.

            )`

        Does anyone is having a solution or fix for this . Thanks in advance

Hi Joyzhao-MSFT ,

Thanks for your reply .

Array index of is working fine . I have checked with below formula which is returning values properly.
=SWITCH(
Array.IndexOf(Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Team.Value,"Dataset1"), ","),","), "Some value") = -1,"NA",
Array.IndexOf(Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Team.Value,"Dataset1"), ","),","), "Some value") = 0, "0",
Array.IndexOf(Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Team.Value,"Dataset1"), ","),","), "Some value") = 1, "1",
Array.IndexOf(Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Team.Value,"Dataset1"), ","),","), "Some value") = 2, "2"
Array.IndexOf(Split(Join(LookupSet(Fields!ID.Value,Fields!ID.Value,Fields!Team.Value,"Dataset1"), ","),","), "Some value") = 3, "3"
)

But when there is blank value or single string I am not able to fetch value inside switch although that formula return value if i use that separately..
