Running a script from a powershell script with conditions - sql

Question

So, I have a script I use for deployments and some of these commands aren't recognized till after sqlps is run, usually I do it manually. I want to automate the running of that script. Here is the script:
$client = Read-Host "Enter Client name"
$date = Get-Date -Format "yymmdd"
$sqlsrvname = Read-Host "Please enter the sql server name"
$deploytype = Read-Host "Is there a server instance? (1) Yes (2) No"
switch($deploytype){
1 {$Instance = Read-Host "Please Enter instance name"
cd -Path $ppath
Invoke-Command .\sqlpatchremote.ps1 -DBServer $sqlsrvname –dbinstance $Instance –client $client –mainline HTFS –datefolder $date –targetenv $sqlsrvname }
2 {cd -Path $ppath
Invoke-Command .\sqlpatchremote.ps1 –dbs $sqlsrvname –client $client –mainline HTFS –datefolder $date –targetenv $sqlsrvname }
default {"Invalid Selection"}
}
When I try to run this script I get this error:
Invoke-Command : A parameter cannot be found that matches parameter name 'DBServer'.
At line:17 char:38
+ Invoke-Command .\sqlpatchremote.ps1 -DBServer $sqlsrvname –dbinstance $Instance
...
+ ~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Invoke-Command], ParameterBindi

InvokeCommandCommand
It tells me its an invalid command when it normally works when I type this in manually, how can I make this work? This script is suppose to install SQL databases on a SQL server. When I run this code manually I just type "sqlps" and then navigate to the directory of the script. Then I run it with the filled in parameters and it doesn't give me an error. I feel like this might be a simple fix to get this to work, but I'm not sure what it is and I wasn't really sure how to ask it. Thanks!

Error:
Invoke-Command : A parameter cannot be found that matches parameter name 'DBServer'.
At line:17 char:38
Invoke-Command rejects parameter DBServer. This means you are passing the arguments to Invoke-Command instead of your script.
To pass the arguments to the script you are invoking, you have to use the -ArgumentList parameter.
Try :
Invoke-Command -ComputerName "targethost" .\sqlpatchremote.ps1 -ArgumentList "-DBServer $sqlsrvname –dbinstance $Instance –client $client –mainline HTFS –datefolder $date –targetenv $sqlsrvname"
EDIT: really not sure about the above syntax for the arguments :( (if anyone could confirm?)
With the arguments in the proper order I've successfully tested it like this:
Invoke-Command -ComputerName "targethost" "scriptpath" -ArgumentList $arg1,$arg2#,...
