EXE Powershell script XML

Hi,

I create new EXE/Script advanced sensor

PS script (ok):

# XML Output for PRTG
Write-Host "<prtg>"
Write-Host "<result>"
                "<channel>Sessions</channel>"
                "<float>0</float>"
                "<value>10</value>"
           "</result>"
Write-Host "</prtg>"

PS script edited (fail)

%i = 10

# XML Output for PRTG
Write-Host "<prtg>"
Write-Host "<result>"
                "<channel>Sessions</channel>"
                "<float>0</float>"
                "<value>%i</value>"
           "</result>"
Write-Host "</prtg>"

Output: This sensor has not received data for x minutes x seconds.

No output to PRTG Network Monitor\Logs (Sensors)

I tried to restart server, services. Error still persist.

Thank You
