 ### Example 1: Adds custom error to application gateway level
 ```powershell
+PS C:\> $resourceGroupName = "resourceGroupName"
+PS C:\> $AppGWName = "applicationGatewayName"
+PS C:\> $AppGw = Get-AzApplicationGateway -Name $AppGWName -ResourceGroup $resourceGroupName
 PS C:\> $customError502Url = "https://mycustomerrorpages.blob.core.windows.net/errorpages/502.htm"
-PS C:\> $updatedgateway = Add-AzApplicationGatewayCustomError -ApplicationGateway $appgw -StatusCode HttpStatus502 -CustomErrorPageUrl $customError502Url
+PS C:\> $updatedgateway = Add-AzApplicationGatewayCustomError -ApplicationGateway $AppGw -StatusCode HttpStatus502 -CustomErrorPageUrl $customError502Url
+PS C:\> Set-AzApplicationGateway -ApplicationGateway $AppGw
 ```
 
 This command adds a custom error of http status code 502 to the application gateway $appgw, and return the updated gateway.
 
 ### Example 2: Adds custom error to application gateway listener level
 ```powershell
-PS C:\> $resourceGroup = "resourceGroupName"

-PS C:\> $customError502Url = "https://mycustomerrorpages.blob.core.windows.net/errorpages/502.htm"

-PS C:\> $listener = Get-AzApplicationGatewayHttpListener -ApplicationGateway $AppGW -Name $listenerName
-PS C:\> $updatedListener = Add-AzApplicationGatewayHttpListenerCustomError -HttpListener $listener -StatusCode HttpStatus502 -CustomErrorPageUrl $customError502Url 
-PS C:\> Set-AzApplicationGateway -ApplicationGateway $AppGw
+ $resourceGroupName = "resourceGroupName"
