Numeric values not being recognize on password

hi,

yesterday shg was able to help me solve this worksheet program. The problem I currently have is all numeric values only are not being recognized on my password column. I have tried changing the cell formats but still problem still there. The program work if an alphanumeric value is declared as password. However if you simply indicate plain numeric values only as password, it returns incorrect values, it like it doesn;t recognize all numeric values. Also how can I make 0000 as a declared password? when I place 0000 on my password column, only one zero value is being displayed instead of four another thing if I happen to place 0123 only 123 is being displayed. Any one please help? I have attached my workbook which has the problem

Thanks,
Stoey
