Hi

I have a scenario where the account currency and opportunity currency can be different. The opportunity currency should be the same as opportunity owner currency. I have to write a trigger for it. Can anyone help me with it.
Highly appreciated.

Hello,

I'm trying to validate the first challenge on this module, "Create a Validation Rule", and I am getting this error: 

"There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: IONRVQWT"

I have tried doing it in my dev org as well as a brand new Trailhead playground. The challenge is really straightforward...any ideas what might be causing this?
