Found the script.
Contributions::date_deposit = [!]
Nope. That pulls all records with a date, not ONLY the records with the SAME date that is listed on the current record.
Any help much appreciated...
It actually finds all the records that have more than 1 contribution for their date.
#Capture current contribution date
Set Variable ($Date ; Contribution Date )
Enter Find Mode
Set Field ( Contribution Date ; $Date )
