Batch Script Powershell Snippet on stopping a website

Question

Don't know much about Powershell, but I have created a bunch of scripts, thanks to Stack Overflow and all people who give examples on how to do something. I have a snippet and it works for checking a URL and lets me know if its up, down, or don't exist by catching the 100 the batch scripts works fine. Here's a piece of that script:

Set CheckUrl=`Powershell.exe -nologo -NoProfile -command "try { (Invoke-WebRequest -Uri http://exceedtst.infarmbureau.com/Exceed).StatusCode } catch { "100" }"`

I use a for /F to get the result. Now I'm trying to do the same thing when stopping a website. What I'm currently trying is:

Set CheckUrl=`Powershell.exe -nologo -NoProfile -command "try { (Invoke-Command -ComputerName WB-EXCEEDA-DEV -ScriptBlock { Stop-WebAppPool -Name Exceedtst).value } catch { "100" }"`  

When I run the entire script I get:

"( was unexpected at this time."

I don't even know if I get the syntax correct even if what I'm trying to do is possible.
