Hi @on2onyekachi, can you add the issue number to the description above? Thanks!!

[on2onyekachi]

Okay @TildaDares, That has been fixed. though this PR has 2 commits for different issues.

Hi @on2onyekachi, it's better if PRs solve only one issue/problem. It's a lot easier to review that way. Thank you!!

[on2onyekachi]

Okay, @TildaDares I really didn't realize there was a pending PR from the same branch. Not until after the push. sorry for that. Please how can I go about redoing this?

[TildaDares]

@on2onyekachi I don't have any experience with splitting commits into different branches but you can checkout this SO answer.
