"There is a wall between you and me."
Translation:Zwischen dir und mir ist eine Wand.
Nearly; Wand is feminine, so it would have to be Es gibt eine Wand zwischen dir und mir.
That's one of the accepted answers.
What is wrong with "Da ist eine Wand zwischen dir und mir." Since we could be talking about an actual wall between us.
"there is..." expresses existence (but not location); the German equivalent is es gibt..., at least for things that are relatively permanently in that location.
da would be used when "there" is used literally, as a location.
So if the sentence would begin with "There stands the wall..." or any other verb where we speak about more than simply an existence of the wall, I could use "da" ?
Or even if the English had "There is a wall there..." with an additional "proper" there.
Could be either, depending on how thick the wall is. (Mauer for thick walls, as in city walls or the outside walls of a building; Wand for walls between rooms inside a building.)
Why doesn't it accept "zwischen mir und dir"? Is there a rule like "you and I" vs "me and you" in English?
The basic rule on this course is not to change the word order.
ein Hund und eine Katze is "a dog and a cat", not "a cat and a dog".
zwischen dir und mir is "between you and me", not "between me and you".
ok, I got that in relation to Duolingo... But is it grammatically incorrect to ever say "zwischen mir und dir"?

No, it's not grammatically incorrect.
Some may consider it a bit rude to name yourself first, but that's a matter of style, not of grammar.
There are accepted translations that include es gibt.
But just the two words es gibt are not a translation for the sentence "There is a wall between you and me".
If you posted the entire sentence that you had written here, perhaps someone can comment on whether there was an error and if so, what it was.
For example, perhaps you got the word order wrong.
But just two words out of context is not really enough to say what was wrong.
