JMeter Beanshell Integer Error

i have problem with Integer in JMeter Beanshell Sampler/Pre/Post processor. I have some array of values, and i want to use each value of this array to set JMeterProperty for next use.

GOAL> have some N rows from query. For Example UPSTREAM column has diff values and i need it save them for next use. Because i will use them for call CMD.exe as parameters by "OS Processes Sampler".

So, if UPSTREAM_1=XXX, UPSTREAM_2=AAA, 
CMD.EXE will looks like: CMD.EXE -upstream_1 -upstream_2, etc.

---

From SQL i got Array of values

COUNT=31
UPSTREAM_#=31
UPSTREAM_1=XXX
UPSTREAM_2=AAA
....

In PostProcessor i set:

${__setProperty(COUNT, ${COUNT_1})};

I am trying this scrpit:

import java.util.*;
import java.text.*; 
import java.io.*;

int max = Integer.parseInt(vars.get(${COUNT_1})); //--COUNT=31, Integer doesnt work
int n = vars.get(${COUNT_1}); //--COUNT=31, this also doesnt work

for (int i=1;i<=n;i++)
{
   ${__setProperty(UPSTREAM_i, ${UPSTREAM_i})};
}

But JMeter log say that it dont know the "INT"

Can somebody help me? Maybe i miss some libs or something. JRE/JDK i have.

UPDATE_1

User Variables all:

COUNT   ${__property(COUNT)}    Count of Rows from SQL Query

Test_Plan:

PostProcessor Log:

SamplerProperties:
variableNames=DATE,DOWNSTREAM,UPSTREAM,COUNT,etc.

This is in Jmeter log now:

UBIK LOAD PACK's solution works :), GOAL updated.
