Hi there. My name is Wes and I am new to this forum! I am trying to create a spreadsheet that will do a bunch of chemistry calculations depending on what is given to you via spreadsheets on my brand TI-nspire CX CAS. Basically I need a way to set a cell equal to zero if a reference cell has nothing input. How are blank cells defined in the nspire? Thank you very much! It keeps outputting "-" when the reference cell is empty.
Blank/Empty Cell Spaces
Summary:functions or programing?
