I accidently deleted a piece of code on my Shopify Store- Please help!

[SharedGalaxy]

Hi there! I am in the middle of building my shopify store and I have 10 days left of my free Trial. Yesterday I was trying to remove the "Review" section on the "Product Page". I accidently deleted "In Themes" The coding heading under one of the "Section Tabs" I was meant to delete 1 line of code and instead deleted the whole review section on Shopify. Can you please help me resolve this. Since I removed it by mistake, on my store I am getting an error message in the preview section on my product page "Liquid Erro: Error in tag section-"Product Reccomendations" is not a valid section type.

Can you please help me resolve this so I can get my store up and running?
