Hi everyone.
Here's my problem:
I've got a table on my gui. All the entries are editable. Whenever I run the program, I should keep in mind that the first cell must be left empty(just an example) while others are filled. But there are times I become careless and accidentally inputted a value on the first cell. So my initiative tells me to delete the number/word I have just inputted. But a "Nan" appears after. I really want to avoid this case. So how can I avoid the Nan even after inputting some value then deleting it? How and where should I program an error dialog so that, no "Nan" can be seen on my table. Thank you very much. God bless

Hi Melvin,
I'm encountering the same problem (R2013a). Were you able to find a solution for this?

Hi jeff, I cannot remember how I solved it. It's been a long time since I had this problem. Maybe, I haven't solve it either. I am really sorry. I am not using MATLAB these days anymore. Good luck. Don't stop exploring.
Regards, Melvin
