Is there any way to check that the credit Card number entered in the cell is either VAlid or not ( I am asking abt the valididity of the Checksum not the validity of teh cRedit Card Number)(
I tyhink its teh Luhans Formula which uses MOD 10
Further more some cards have 16 Digits some have 14 Digits
