How to change grams of meal on MFP

JoeyFitness1718

So I’ve found the meal I’ve eaten and I’ve clicked it but the amount isn’t right. I want to change the amount from 100g to 900g but it won’t let me. Not sure how to do it, any help would be appreciated

Can you change the servings to 9, so then it’s 9 servings of 100 g? Or, if you click on the 100 g, it will often give you other options like 1 g, or ounces, etc. You can choose 1 g, then make it 900 servings.
