Hello
I done the program below for a CD database but im having a few problems with some of the functions can someone please help me out here ,, ::
First this is when i enter a record i can enter the first set but when i try to enter the second record it only let me enter the first two fields, which are artist and album it then just keeps asking wether i want to continue or not.
Second thing is i cant for some reason enter spaces for the fields, for example an artist with two names will need space in between, every time i use space it reads it as part of the next field.
I would apreciate any help neone can give . please.
