Error TextBox

After migration from Nav2005 to Nav 2009 I have one error message on Form 5741 - Transfer Line.

When inset a quantity value i get one message:

The TextBox named ‘No.’ specified a nonexistent ID (1) as a control upward.

How can I solve it?

I tried to change Parent control but no success.



Maybe this post helps you:

Thanks to all.

The Problem was solved with a correction on object Form 342.
