Iterative Calculation during Load in Qlik

[carlcimino]

Pulling some data that has 4 columns that I want to turn into 4 rows.  I started by using an iterative loop where i = 1 to 4.  However I want to use the $(i) within a formula to calculate the weighting of each base prem 1-4 to the total.  As soon as I insert this into the SQL I get an error - my script log is attached.  Any help would be greatly appreciated.

(a.BASE_PREM$(i)/(a.BASE_PREM1+a.BASE_PREM2+a.BASE_PREM3+a.BASE_PREM4))*a.TOT_TRM_PRM as VEH_TRM_PRM

Here's my working script before adding the formula.

LIB CONNECT TO 'PRS_Auto_Inforce_AIP';

for i = 1 to 4

CAAS:
load

where len(trim(MODEL_YEAR))>0

cast(replicate('0',12-len(ltrim(rtrim(a.POLICY_NO))))+ltrim(rtrim(a.POLICY_NO)) as varchar(99)) as POLICY_NUMBER

Store CAAS into 'lib://PRS_Auto_Inforce_QVD/CAAS_CAR_$(i).qvd' (qvd);

drop table CAAS;
next i;

To turn columns into rows you will want to use the CrossTable load prefix. Read up on CrossTable in the help:

Thanks Rob!  I got the crosstable load to work for transposing 4 columns to 1.  When I add another set of 4 columns (highlighted below) the script runs but it returns nothing for those 4 new columns.  Is there something else I have to qualify?

crosstable(UNIT_ID, VIN_NUMBER, 16)
load *
