create a list boxwith calculated values

[lorita2021]

hello,
I have a field which contains the dates of the last 3 months from today's date.
I want to create from this field a personalized list box which contains the following
3 labels:
- the last 30 days (select all the dates of the last month)
- the last 60 days (select all the dates of the last two months)
- the last 90 days ( select all the dates of the last three month°
I used this expression :
=if(CS_LastUpdate >= today()- 30, 'the last 30 days',
if(CS_LastUpdate >= today()- 60, 'the last 60 days',
if (CS_LastUpdate >= today()- 90, 'the last 90 days')))
But it gives me an incorrect result.

for the label "last 30 days" it gives good results but for the last 60 days for example, it selects only the second
last month without taking into account the last month. Same for the label "last 90 days", it select all the dates of
the 3rd last month without taking into account the two months which are before. Any solution please ? 

Thanks in advance

Sometimes before, I have replied with my approach. Please check if this suits your requirement too.

Try the below script

T1:
LOAD Date,
if(date(Date,'MMDDYYYY')>=Today()-29,'the last 30 days') as days_30,
if(date(Date,'MMDDYYYY')>=Today()-59,'the last 60 days') as days_60,
if(date(Date,'MMDDYYYY')>=Today()-89,'the last 90 days') as days_90

FROM
[C:\Users\NM\Desktop\Scenarios\19 feb21\New Microsoft Excel Worksheet.xlsx]
(ooxml, embedded labels, table is Sheet1);

T2:
CrossTable(Days,Data,1)
load * Resident T1;
DROP Table T1;
