Hello ,

I am working on MATLAB GUI using guide. I have an edit box which takes the input(Range : 1 to 100) from the user. When i enter the data in the edit box as 200, before saving the data i want to check whether the entered number lies within the specified range.If the entered number is not within the specified range then i want to display a message that

"The entered number is not a valid number" and then clear the edit box to enter the new number.

I am using the errordlg() function to display the error message. But i am not able clear the edit box and re-enter the new valid number .

It would be grateful if you let me know how this is done.

Looking forward to hear from you.

Thanks

Pankaja
