REXX DB2 issue

Hello!
I am executing the below code to fetch the TSNAME for a table from database . My requirement is to display TSNAME on panel after user enters SSID and table name in the panel.
The issue is that the TSNAME is always blank on panel. I am not sure whether the problem is with DB2 query or my REXX program / panel. When I am executing the query in QMF it is fetching the result correctly. Please help me with this.

The code is as shoen below.

/*REXX*/
/*TRACE I */

" ISPEXEC LIBDEF ISPPLIB DATASET ID("USER.REXX.UTILS")" ;
IF RC \= 0 THEN
CALL RTNTHROWERRORMESSAGE 1, RC;

"ISPEXEC DISPLAY PANEL (PNLTSNME)";

/* GET THE INPUTS FROM THE USER */
"ISPEXEC VGET (SSID, TBNAME) PROFILE";
TBL_NAME = "'" || TBNAME || "'"

ADDRESS TSO "SUBCOM DSNREXX"

S_RC = RXSUBCOM('ADD','DSNREXX','DSNREXX')
IF S_RC <> 0 THEN
SAY 'PROBLEM LOADING DB2 ENVIRONMENT'
ELSE
ADDRESS DSNREXX
"CONNECT" SSID
IF RC = 0 THEN DO
SQLSTMT = "SELECT TSNAME FROM SYSIBM.SYSTABLES
WHERE TSNAME <> 'SYSDBAUT' AND
NAME =" TBL_NAME

ADDRESS DSNREXX "EXECSQL PREPARE S1 INTO :SQLDA FROM :SQLSTMT"
ADDRESS DSNREXX "EXECSQL DECLARE C1 CURSOR FOR S1"
ADDRESS DSNREXX "EXECSQL OPEN C1"

IF RC = 0 THEN DO UNTIL (SQLCODE <> 0)
ADDRESS DSNREXX "EXECSQL FETCH C1 USING DESCRIPTOR :SQLDA"
SAY SQLCODE
IF SQLCODE = 0 THEN
ADDRESS DSNREXX "EXECSQL FETCH C1 INTO :PTSNAME"
END
END
ADDRESS DSNREXX "EXECSQL CLOSE C4"
ADDRESS DSNREXX "DISCONNECT"
S_RC = RXSUBCOM('DELETE','DSNREXX','DSNREXX')

/* TO DISPLAY THE PANEL */
ADDRESS TSO "ISPEXEC DISPLAY PANEL (PNLTSNME)";

ADDRESS TSO "ISPEXEC VPUT (SSID, TBNAME, PTSNAME) PROFILE";

RETURN;

why display the panel and then populate the variables?

And do the panel variables match the REXX variables ?

I was displaying the panel before populating the values.
It's working fine now.
Thanks Dick!!
