How to write script to count the last 30 days for each date and load into temp table

[QlikSenseLearner]

I am having trouble in loading the last 30 days volume for each date.  I am getting the same count for all the dates. But it should be different count for each date , it should represent the count of serviceid's  for past 30 days prior to each of the dates loaded through Variable. example:

date	30day volume
8/8/2022	11970
8/7/2022	12300
8/6/2022	12890
8/5/2022	11200
8/4/2022	12100

Please help me to find the solution. I am using the below script:

Let vMinDate = num(Date#('11/01/2021','MM/DD/YYYY')) ;
let vMaxDate= num(Date#(today(),'MM/DD/YYYY'));

For X=$(vMinDate) to $(vMaxDate)

Let Y= $(X)-30;

NoConcatenate
FinalCount:
Load Sum(ServiceIdCount) as 'TotalCount'
Resident XYZ
where Floor(Date)>=$(Y) and
Floor(Date) < $(X)
;

Let i = peek('TotalCount', 0 ,'FinalCount');

Temp:
Load
'$(X)' as 'Dte', '$(i)' as 'Cnt';

drop Table FinalCount;

Next X

drop table XYZ;

I am getting below result:
