Display most recent value based on date selection of date picker

[ineedhelp]

I have this dataset, in this example, when I choose the range of date picker on qlik sense from '27-Oct-24' to '2-Nov-24', what I need is to display the latest value of column population_m, which is '781'. I tried to sum max date but it sum all the value from '27-Oct-24' to '2-Nov-24'

Here is the data set

Area	Type	flock	current_state	date_calc	age_D	age_W	mortality_F	mortality_M	population_f	population_m
L4	MI	A	Growing	27-Oct-24	28	5	1	0	1,154	783
L4	MI	A	Growing	28-Oct-24	29	5	0	1	1,154	782
L4	MI	A	Growing	29-Oct-24	30	5	0	0	1,154	782
L4	MI	A	Growing	30-Oct-24	31	5	1	0	1,153	782
L4	MI	A	Growing	31-Oct-24	32	5	0	0	1,153	782
L4	MI	A	Growing	1-Nov-24	33	5	1	0	1,152	782
L4	MI	A	Growing	2-Nov-24	34	5	0	1	1,152	781

Sum ({< date_calc = {'$(=date(maxstring(date_calc))'} >}population_m)

(I am assuming your date_calc is a field and that it is a date value and not only a string. )

Hi, you can use FirstSortedValue(population_m,-date_calc)

Max should work also: Only({<date_calc={"=Date(Max(date_calc),'D-MMM-YY')"}>} population_m)

The FirstSortedValue(population_m,-date_calc) work, somehow max is not work as I expected, thank you
