I have A problem in my case 4. For example, When I tried to delete vector record, WHATEVER I insert AB111 BB111 CD111, EVEN I insert the GH111, AS321, ND446 it always shows "You entered an Invalid Employee ID, Which is not in our record: Please re-enter Employee ID to Delete a record: ".

Here is "personnel.dat", Plz saves it and helps me to figure out.

GH111 Allan Barry 36.7 80.3 0.15 2 AS321 DeMann Stan 34.5 28.95 0.16 0 JK290 Denvers Kara 55.6 45.66 0.055 0 NG201 Ivy Samantha 47.5 70.91 0.05 1 ND446 Joneski Kasey 44.5 30.5 0.03 2 KH111 Kent Clark 40 33.5 0.01 0 HJ111 Oliver Ted 27.88 33.11 0.04 1 HJ505 Smith Alias 40 45.6 0.11 3 ZJ319 Wayne Bruce 55.7 75.66 0.095 1 JU105 Williams Judy 20.4 44.5 0.03 3
