Variable set in Script editor cannot show as Measure in table

[43918084]

I have loaded below script in QS, followed by a "Let" for calculation of variable.  However, when I try to apply the variable in table, it shows "-" for all rows.  Hope I could get some guidance.  

[Cust_Bal]:

Try defining the variable as a string.  Note that you will need to use 2 single quotes within the string.  Like this:

let Mov_GCV = 'Sum(IF(Stage_Move = ''New'',Cur_Bal,
IF(Stage_Move = ''Payoff'',Lst_Bal*-1,
IF(Stage_Move = ''Same'',Cur_Bal-Lst_Bal,
IF(Right(Cur_Stage,1)=Right(Stage_Move,1), Cur_Bal, IF(Right(Lst_Stage,1)=Right(Stage_Move,1), Lst_Bal*-1))))))';

Then, in the measure expression, $(Mov_GCV).
