[GAP Forum] A Question about For Loops

[Minghui Liu]

Sorry the above message was incomplete.

The error message is

Error, illegal access to record component `obj.x'
of the object <obj>. (Objects by default do not have record components.
The error might be a relic from translated GAP3 code.)       called from
<compiled or corrupted statement>  called from
<function "unknown">( <arguments> )
 called from read-eval loop at line 28 of *stdin*
you can 'quit;' to quit to outer loop, or
you can 'return;' to continue

Anyone could help me with it?

Many thanks!!
