Powershell ISE - Variable not interpreted

I am experimenting with the following script in Powershell ISE, but this returns an error when executed.

$computerName = Read-Host "Enter name of remote computer"
psexec \\"$computerName" cmd

The Read-Host part works fine, but when it moves to the psexec line it returns 

Enter name of remote computer: Computer

psexec : 
At line:2 char:1
+ psexec \\"$computerName" cmd
    + CategoryInfo          : NotSpecified: (:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

PsExec v2.11 - Execute processes remotely
Copyright (C) 2001-2014 Mark Russinovich
Sysinternals - www.sysinternals.com

So it seems that the script is not passing the value of $computer. I have tried various " ' combinations to no avail.

Any help would be much appreciated, I'm rather novice at powershell scripting.

To expand on some of the other answers, a method a coworker showed me for more complex psexec strings is as follows:

#Use Psexec to Allow all remote connections and Enable PSRemoting
$psexec = "psexec -accepteula \\"+$targetIP+" -u "+$localadmin+" -p "+'"'+$str+'"'+' -h powershell.exe "&{"Set-Item wsman:localhost\client\trustedhosts -Value * -Force" ; "Enable-PSRemoting -SkipNetworkProfileCheck -Force"}"'
invoke-command -ScriptBlock {cmd /c $args[0]} -Argumentlist $psexec

While the above code actually calls psexec on the remote machine then delivers two powershell commands, the problem of authentication causes all sorts of crazy errors in PS.

Hope this helps someone or the OP.

right, I tried this, seems to work:

$computerName = Read-Host "Enter Name of computer"
$cred = Get-Credential
psexec \\$computerName -u $cred.UserName -p $cred.GetNetworkCredential().Password ipconfig 2> $null #hide errors

success

You don't need to quote anything. PowerShell will quote automatically if needed.

psexec \\$computerName cmd
