Creating a default within a repeat group

[Kal_Lam]

@asadmisgis, maybe you could do it as outlined in the post discussed previously:

Dynamic defaults within repeat group

Thank you! I wrapped my initial formula in the once() operator and that did the trick. The way I understand it, the once() checks whether the value is empty and if it is, passes on the expression within the brackets. Once the user enters a value, ODK passes on without doing the calculation. As a result I can save without the ‘’ in the formula deleting the data that was entered. Here’s a copy of the xls if it can help anyone out there! dynamic_default_test.xlsx (17.6 KB)
