As the title states, would you mind teaching me why this sentence is grammatically correct?
"I would like to cancel the job that I had ordered"
The reason I ask is that the below sentence doesn't sound wrong to me, without the "had":
"I would like to cancel the job that I ordered"
Lastly, does the below sentence have the same meaning as the first example? If so, what is the grammatical difference?
"I want to cancel that job I ordered"
