Repeating table values of Textfield/Label not visible in able

[Joppel]

Hello experts!

I'm in the process of creating a repeating table based on Shane Young's example.

In the table I have comboboxes and by selecting the comboboxes other text fields / labels are automatically filled with data.

When saving, however, the data in the text fields disappears, because by default I have set a filter depending on the comboboxes.

How can I best solve this that after creating a new block, the value becomes Parent.something?

I'm working with the information you have provided now. I might need to understand the problem further, however, based on Shane Young's video, I'd assume you are populating the table fields from a Collection that start with a blank row;

1. Set the Default value of the text/label to be ThisItem.<column name of data source>

2. Patch the collection with the values you are collecting

It is true that I start the table with an empty row.

However when I set the Default.Value of the text / label to:

ThisItem. <Column name>

I am not getting the value I filter from the comboboxes I need to calculate the amount.

That is why I now have the following in the text / label:
LookUp (Unit Rates, Title = SelectItemDescription.Selected.Result, UnitPrice)

The text / label field should  after patching to collection change to:

ThisItem. <Column name>
