I'm working with the following problem (much simplified).

DOCUMENT() loadMacros( "PGstandard.pl", "MathObjects.pl", ) Context("Numeric"); $a1 = List( (1,2) ); $a2 = List( (2,3) ); $ans = List( $a1,$a2 ); TEXT(beginproblem()); Context()->texStrings; BEGIN_TEXT ans = \{ ans_rule(15) \} END_TEXT Context()->normalStrings; ANS( $ans->cmp() ); ENDDOCUMENT();

In this, the checker allows the lists `(1,2)`

and `(2,3)`

to be entered in either order, but requires that the inner lists `(1,2)`

and `(2,3)`

be entered in the order given.

I'm sure there is an obvious reason why this is, and thus an obvious fix. But I'm not seeing it. How do I allow the inner lists to be entered in any order?

Thanks,

Gavin
