Running a command written Ad Hoc within an expression

[EliAttiaQlik]

Hi all,

I want Qlik to run the content of the command I wrote. Is this possible?
For example, inside the Expression I wrote:
'(' & Concat ('('& [CumulativeReturn],'+1)*',[CumulativeData]) & '+1)-1)'
And I want Qlik to execute the command I wrote

Thanks.
