Is there a function that saves the last value inputted with query? - google-apps-script

Question

=IF(Summary!H2="October",QUERY(Summary!L2))
Hello,
I was wondering if it’s possible to record the last inputted value with a query function
As seen in the code above, when October is selected in the summary sheet, cell H2 - the cell with the function (above) outputs what is written in the summary sheet, cell L2
When I select a different month, the cell (where the code is written) changes to FALSE
Is there any way to make value_if_false equal the last value inputted into L2 when the selected month is changed?
If further proof is needed please let me know
Thank you,
Gabe

example
Don't know if this is what you mean, here I have created an example, where data is stored in the 'data' sheet, and the QUERY function is placed in the 'main' sheet.
B1, B2 is the condition inputs, I assume you want to sort your data by date, in that case, you will need a start day and an end day.
the QUERY formula will be something like this:
=QUERY({data!A:F},
" WHERE Col1 IS NOT NULL "
&" AND Col1 >= DATE '"&TEXT($B$1,"yyyy-mm-dd")&"' "
&" AND Col1 <= DATE '"&TEXT($B$2,"yyyy-mm-dd")&"' "
)
With this QUERY formula, the output data will change according to the date selected in B1 and B2.
Just make sure that the date column of your data page is formatted as date, otherwise google sheet QUERY will not be able to recognize the data as date.
