Creating or adjusting an entry in database?

tracymayo1

I weigh everything I eat, and sometimes have issues finding the right entry.
Sometimes I want to just edit an entry I know if wrong to include the right information, and add my initials (TM) at the end so I can recognize it.


What I have NOT been able to figure out is how do I enter information in 100g AND 1 g? Like how do I make sure that there will be a "drop down" when I save it? And when I do get the information to do this, will the site break down the 100g info to fit for each gram? or do I have to divide everything by 100 myself and re-enter it?

Can anyone help? show me SS?
