Trouble with modifying Records for multiple items

Hi,

I am pulling data using the following formula for my repeat list

SELECT(data.washing,IS_EMPTY(data.washing[0].fields.Out_Date))

In the repeat list, the records that need to be modified are displayed using the currentfields.(itemname) formula.

Now for the update record flow, I am not sure which variable/formula to use for the ‘record properties’. I tried a bunch of things but nothing worked. Any tips in the right direction would be highly appreciated. Thanks
