ValueList inside If statement?

[Anonymous]

Hi all,

I have the next simple ValueList method:

ValueList('one', 'two')

which works fine if I create a master dimension with it. However, if I put this method inside a If statement:

If(1=1, ValueList('one', 'two'), 'three')

the master dimension returns a null value:

Does anyone have an idea of why does this happen?

Thanks,
