hi, i'm having a problem with errorproofing. K E.g. if there are 3 numbers that i want from the user. they enter the first number correct, but they make a mistake on the second number, i error trap it so it an errorwindow pops up. but when i say loop exit when hasch end loop userinput(procedure) it will start from asking the first number again. is there a way to continue the procedure from a specific point? |

so that you check to see whether you have gotten the number before. |

Do you know what boolean variables are? Think about it. Work it out. Yourself. hint: Asian left one line out of that if statement. |
