Task Scheduling Script - Need help with passing the scheduled command (variables are not being evaluated)

Question

Hi Everyone,
I'm trying to get a simple task scheduler script to work for me and can't get the command I need passed to the scheduler to evaluate properly.
Here's the script:
###Create a new task running $Command and execute it Daily at 6am.
$TaskName = Read-Host 'What would you like this job to be named?'
$Proto = Read-Host 'What is the protocol? (FTP/FTPS/SFTP)'
$User = Read-Host 'What is the user name?'
$Pwd = Read-Host 'What is the password?'
$Server = Read-Host 'What is the server address?'
$NetworkDir = Read-Host 'Please input the network location of the file(s) you wish to send. Refer to documentation for more details.'
$RemoteDir = Read-Host 'Please input the REMOTE directory to which you will upload your files. If there is none please input a slash'
$Command = 'winscp.com /command "option batch abort" "option confirm off" "open $Proto://$User:$Pwd@$Server" "put $NetworkDir $RemoteDir" "exit"'
$TaskAction = New-ScheduledTaskAction -Execute "$Command"
$TaskTrigger = New-ScheduledTaskTrigger -Daily -At 6am
Register-ScheduledTask -Action $TaskAction -Trigger $Tasktrigger -TaskName "$TaskName" -User "Administrator" -RunLevel Highest
Write-Host "$TaskName created to run Daily at $TaskStartTime"
What's messing up is the $Command creation, the command needs to have the quotes around "option blah blah", but if I wrap the whole line in single quotes the variables that are evaluated for the "open blah blah" strings (which also need
to be inside quotes) and the "put blah blah" string are not being evaluated properly.
I've dorked about with different bracketing and quoting but can't nail the syntax down, could someone point me in the right direction? My Google-fu seems to be lacking when it comes to nailing down this issue.
Thanks

Hmmn, closer. I'm getting this error now:
+ $Command = $tmpl -f  $User, $Pwd, $Server, $NetworkDir, $RemoteDir
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (winscp.com /com...t {4} {5}" exit:String) [], RuntimeException
    + FullyQualifiedErrorId : FormatError
And the command being added to the new task looks like this:
winscp.com /command "option batch abort" "option confirm off" "open ($Proto)://($User):($Pwd)@($Server)" "put $NetworkDir $RemoteDir" "exit"
Here's the current state of the script. I get what you're doing to try to bypass the quotes issue, using an array. I'm just not awesome at this yet sooooooo...
$TaskName = Read-Host 'What would you like this job to be named?'
$Proto = Read-Host 'What is the protocol? (FTP/FTPS/SFTP)'
$User = Read-Host 'What is the user name?'
$Pwd = Read-Host 'What is the password?'
$Server = Read-Host 'What is the server address?'
$NetworkDir = Read-Host 'Please input the network location of the file(s) you wish to send. Refer to documentation for more details.'
$RemoteDir = Read-Host 'Please input the REMOTE directory to which you will upload your files. If there is none please input a slash'
$tmpl = 'winscp.com /command "option batch abort" "option confirm off" "open {0}://{1}:{2}@{3}" "put {4} {5}" exit'
$Command = $tmpl -f $User, $Pwd, $Server, $NetworkDir, $RemoteDir
$TaskAction = New-ScheduledTaskAction -Execute $Command
$TaskTrigger = New-ScheduledTaskTrigger -Daily -At 6am
Register-ScheduledTask -Action $TaskAction -Trigger $Tasktrigger -TaskName "$TaskName" -User "Administrator" -RunLevel Highest
Write-Host "$TaskName created to run Daily at $TaskStartTime"
