Learn Functional Programming by building a spreadsheet

I’ve completed the project, but I have trouble using range. If I input =sum(a1:c3) nothing happens. Internet Explorer browser console says:
Uncaught TypeError: Cannot read properties of undefined (reading ‘value’)
Chrome browser doesn’t say anything.

Hi @tranphamholistic

Try using uppercase letters.
Or to debug, check what is in cells A1,A2,A3,B1,B2,B3,C1,C2,C3

Happy coding

Thank you! It works with uppercase. I just need to use toUpperCase() on character in the elemValue function. It’s fixed.
