Hi,
Sorry for the delay. I had to recreate the form. It is zipped together with an excel data file. This is probably going to need some explanation.
Here's how it's supposed to work...
First, think about the Excel file as a list in SharePoint.
The drpdnRecordID control on the form uses the [Record ID] column; the drpdnLineItem control on the form uses values in the [Line Item] column filtered on the chosen Record ID; the read-only txt[year] fields on the form (2015, 2016, 2017, 2018, 2019, 2020) use the corresponding year columns.
When the user chooses a Record ID from drpdnRecordID, the drpdnLineItem should only list those line item values corresponding to the chosen Record ID. When the Line Item is chosen, the year values should populate the read-only year controls. Separately, not connected with the fields, the user must manually add proposed change values beneath each year value.
If the user needs to add a new Line Item, they add a new (inner) repeating section, choose a different line item which should populate the year controls with values corresponding to the chosen line item and then add their proposed changes. And, so on....
If the user needs to add a new record id, they add a new (outer) repeating section and repeat the process.
Is there a better way to do this than uses nested repeating sections?
Thanks in advance for your help,
