Try something simple first: Under Food; Add Food; Press + in the top right hand corner; Type in a name {I use Carb. (grams)} and save the food. Then under Pick Food(s) you should be able to pick the food (when done successfully you will see a check mark on the right hand side), then press Add Log at the top left, this takes you back to Add Log menu where you should be able to input the grams. I hope it helps!
