Well I've the box, and the length of my variable is also displayed in it, so the box exists and is properly tagged... Could it a be a problem of updating datas? I mean, maybe by moving the slider I reset some of the needed inputs in the structure...

No, not unless you did something stupid like use rmfield to get rid of
the edit3 field of your handles structure. Just set a breakpoint at
that point in the code and examine the handles variable. Are you
ABSOLUTELY sure that handles has an "edit3" field AT THAT SPECIFIC
LOCATION IN YOUR CODE? I'd bet it doesn't. If it does, then the
value for that handle (handles.edit3) must be a number that no longer
represents a valid control on your figure. Maybe you did something
like delete(handles.edit3) to blow away the control but leave the
edit3 field still in handles, or something strange like that. Search
your code and make sure you know what all clear() and delete()
commands are doing, and their possible ramifications and side effects.
