Input "data" to a specific numbers doc / month sheet-

I would like to run an apple script. get a popup (which is done already) and take that value and add it to a specific numbers document and create a sheet name by "year / month and add the data to the first row and cell. And to the next cell to add the current date that it has been added.

and if I run the script again. add the new "datas" to a row below.

visual example:

so popup input. 60 then autoadd current date to second column. and the 60 to the first one which I inputted.

and if I add a new input then add it to the next row etc. And when It's a new month create a new sheet with year/ month name

Please help 🙂

I'm new to this.

Thank you!!!
