How to get a particular method value from a Collection table in a report

Dear experts,
I am trying to create a field in a pre-existing report. and the value of that field needs to be a CollectionField. I created the following code, but its not working. interesting if i use the same collection as a table in a Entry mode field (say voucher entry) then it works fine. but in the report the value comes up blank. Can someone please suggest what could i be doing wrong here.

Here is my code:
[#Line: LEDBILL SubTitle]
Add: RightField: Comm

[Field:Comm]
use:NameField
set$$CollectionField:$Pmt_Amt:1:Commission)
width:22
Background:yellow

[Collection:Commission]
Type : Vouchers: VoucherType
Child of : $$VchTypePayment

Fetch: PartyLedgerName

By : Creditor_Name : $PartyLedgerName
Aggr Compute: Pmt_Amt : Sum : $$FilterAmtTotal:AllLedgerEntries:IsDeemedPositive2:$Amount

Format: $Creditor_Name, 20
Format: $Pmt_Amt, 20

[System : Formula]
IsDeemedPositive2 : $IsDeemedPositive
