## FYI: exact digits required for autocoding

Added by Devin Casenhiser over 9 years ago

Just in case someone makes the same mistake:

When you use the AMCcode option to have students code in their student number, it appears students have to code **all** the boxes. That is, you can't provide, for example, 10 boxes if the student has a 7 digit student number. The unfilled boxes will cause AMC to NOT auto recognize the student id. (I know a silly thing to do, but I have two sets of students -- one set has 8 digit IDs the other has 6 digit IDs so I'll just get those with 6 digits to add 0s -- easy fix).

Cheers!

The unfilled boxes will cause AMC to NOT auto recognize the student id.

More precisely: if all boxes are unfilled for a particular digit, the value 0 will be used. But the code 0001234567 is not the same as 1234567 for AMC - perhaps I will change this...

From revision r1143, AMC removes leading zeros from students IDs before comparing them, so that this problem should not arise. Thanks for pointing it out!
