I have an object variable (let’s call it variable X), and It has multiple fields, a, b, c, d.

Field D, the field I want to change, is an array of 3 things.

How do I update what’s in example, #0 of field D via a workflow, but NOT #1 and #2? i.e. instead of “I’m very excited to share…”, I want to change it to something else.

I tried to do this but it didn’t work.

It ended up like that:

Or is there something else I have to do altogether rather than trying to change the variable value in workflow?

I had a similar question about updating a single object in an array recently. I solved it using Co-Pilot but I’d like to know the no-code answer.

I have an ‘on change’ workflow attached to the input field, configured as shown below. I have it configured to “Update one item” in the array using the index of the current item in the datagrid. I think that piece is right? But I can’t figure out what to put in the Value field. I tried asking the Co-Pilot to generate some custom js to updat…

You seem to have the correct path, can you check the value you are using for the second parameter? It may explain the extra 0
