Check table with both numerical and "DNE" entries?

I want students to enter limit values into a table, some of which exist and some don’t. I told them to enter “dne” if the limit doesn’t exist, but is there a way to code it to check that? I have it in math format, so I guess I have to “read” the latex for dne or DNE, etc.

NEVER MIND. I figured it out… was using cellNumericValue but in the cells that get dne I just used cellContent and have check for either dne or DNE and it works! :slight_smile:

You could also use not(isDefined(table.cellNumericValue(1,2))), or something similar. You won’t get the text difference that way.
