String to Numbers

Hi all I set up Vref approach flap speeds with 'string' for the FMC approach page. %((L:VrefFlapSelect,enum) 1 == )%{if}%('174' '169' '164' '159' '154' '148' '142' '135' '129' '122' 10 (L:VrefCalc,number) case)15°/%!s!KT%{end}% It all works OK, But now I want to use the same numbers to set the Vref bug in the PFD. Can I convert the string numbers to a L:Var,number or will I have to recode it all?
