im currently working on a program that when a certain number is inserted in the first TEdit and a calculate button is clicked the second TEdit displays the total and the third TEdit displays the mean of the total.
but when i run the program and click on the calculate button i get a " ' ' is not a valid float" error.
i've gone through the code and even had a look at the string grid example but i still get the error.
what could be the cause of this?
