A colleague also reported that the function List shows the value stored in repetition 0.
I can confirm that this happens with FileMaker 11 on Windows XP.
I don't know if it can help but, in the output of the function List, the value of repetition 0 is always shown as second.
Thank you for your post.
I am able to replicate the issue on FileMaker Pro 11.0v4 for Mac and FileMaker Pro 11.0v3 for Windows. In essence, you can enter a 0 (zero) or a negative value for the repetition number, and although none of the existing data gets modified, the information is added to the contents of the field but cannot be accessed. Even with Set Error Capture turned on, Get (LastError) returns 0.
I have sent your posts along with my findings to our Development and Testing departments for review. In the mean time, do not use a zero or negative value for a repetition number.
