if you have already declared it as shared array in the subreport, after populating it, use the same declaration in the main report ... after the subreport has been run and the values are available for use.

Thanks for the response. I have following code in subreport

WhilePrintingRecords;
shared stringvar Array labelquest;
numbervar i:=1;
Redim labelquest[3];

if condition 1 then
     labelquest[1] := 'condition'
else if condition 2 then
      labelquest[2] := 'condition'
else if condition 3 then
      labelquest[3] := 'condition';
For i := 1 to 3 Do
(
   labelquest = labelquest
);

labelquest[1] + ' ' + labelquest[2] + ' ' + labelquest[3]

I don't think I have written above syntax in most correct manner (suggestion are always welcome)

It display the database value in subreport and I have following code in my main report after the subreport

WhilePrintingRecords;
shared stringvar Array labelquest;
ReDim labelquest[3];
labelquest[1] + ','+ labelquest[2] + ','+labelquest[3]

and I am not getting any value in the main report..

Help me what am I doing wrong..

when you redim, you erase the array. You don't need to redim it in the main report, just access the members of the array.

Thanks again..

I realized the redim keywork so my code now reads

WhilePrintingRecords;
shared stringvar Array labelquest;
labelquest[1] + ','+ labelquest[2] + ','+ labelquest[3]

My first two label values getting overwritten by the third label, so I am getting same label three times. and if I try to make it as drilldown I get the 'subscript must be between 1 and the size of the array.'

Sorry to bother.. but I am totally lost.

For i := 1 to 3 Do
(
labelquest = labelquest
);

I don't think that this code is needed at all. You have already assigned the value, and you aren't assigning as the syntax for that would be :=.

and you probably want to break this into 3 if statements, as only 1 gets a value:

if condition 1 then
     labelquest[1] := 'condition'
else if condition 2 then
      labelquest[2] := 'condition'
else if condition 3 then
      labelquest[3] := 'condition';
