Hi all,
So I am trying to create a text input that only updates a specific record on a SharePoint List. The text input will never need to update a different row/record on the SP list. It's main use is to customise the app for repeat use on other projects without another user needing to update labels on multiple reporting tools that are linked to the same SP List.
Below is the SP List:

Below is the text input names:

Below is the patch code to update the SP list:
Patch(
'Project Details (Project Log)', LookUp('Project Details (Project Log)'.Title,"Customer:"="Customer:"),
{
'Project Details': 'TextInput_Customer Name'.Text
}
)
I don't understand why it's not working as I'm still fairly new to power apps and the debugger is not throwing up any errors. I have already checked similar articles and the "Title" column is not ticked as "required", (although there might be deeper SP settings which force it to be with it being the first column in the SP List).
The only error I do get is the below when I press the "Save" button which uses the patch code.

Thanks in advance for any help 🙂
