Alright, this one has me stumped. I have re-played two different videos a total of three times plus carefully looked at my code for syntax errors, missing quotes, etc. I even tried single and double = signs (it should be ==). What am I doing wrong? My if statement should be good. Help!
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
if grocery_item.has_value?("Bread") == true
grocery_item = {"food" => true}
end

# there's a problem with this line
grocery_item = {"food" => true}
# instead of just setting the value for "food" key
# you're essentially assigning grocery_item to a completely new Hash
# change it to
grocery_item ["food"] = true

21,598 PointsThis is how it should look:
if grocery_item.has_value?("Bread")
grocery_item["food"] = true
end
You do not need to specify "== true" because "has_value?" already returns true if such item is present.

10,791 PointsGuys, this still did NOT work. I tried both with brackets and parenthesis and it still doesn't work. I'll try to paste below (I'm trying to stick to the same forum post and not a new forum post):
if grocery_item.has_value?("Bread") = true
grocery_item["food"] = true
end

21,598 PointsRemove the " = true" in the first line. Remember that one equal sign assigns a variable, two equal signs (==) checks equality. And as i mentioned earlier You do not need to specify it, the has_value? already returns true if it finds "Bread".
