Adding items to a SharePoint List

[Fusion]

Hi guys, 

I know there are a lot of people asking for help with this sort of thing and I have gone through alot of the posts and tried them already hence why I have come here to post. 

I have a form (PowerApps Phone) like below

 

The add button (btnAdd) has a command behind it when they click it (OnSelect). This is where I am running into issues. I want to push whats in the text boxes into a SharePoint List which has the following fields (Title, Brand, Model, Serial, Asset). 

The code I have: Patch('Tech-Bench Items', Defaults('Tech-Bench Items'), Title:lblJobID,Brand:txtBrand,Model:txtModel,Asset:txtAsset})

lblJobID is gotten form the previous Screen of the app that takes customer details.

When I click Add I get the little red X in a circle which states "An unkonw error occurred". 
I have been at this since 9am this morning and dont want to let it beat me.

Thanks for your help in advanced.

And after some time looking at it I found out why it was not working. 

The code I was using did not have .Text after each of the items, once I put that in everything worked.
