How to deploy templates exported from a resource group in Azure RM?

I'm trying to get started working with Azure RM templates and having some issues when trying to deploy templates exported from a resource group in the Azure portal.

When I try and deploy my exported template I get the following error:

{"telemetryId":"5d4b90de-18fd-432f-a6c7-cfa65eb22bc8","galleryItemId":"MyGalleryItem","createBlade":"DeployToAzure","code":"InvalidTemplate","message":"Deployment template validation failed: 'The template resource 'myVM-nic' at line '1' and column '3020' is not valid: Unable to evaluate template language function 'resourceId': function requires exactly one multi-segmented argument which must be resource type including resource provider namespace. Current function arguments 'Microsoft.Network/virtualNetworks/subnets,vnet-myVnet/Subnet'. Please see https://aka.ms/arm-template-expressions/#resourceid for usage details.. Please see https://aka.ms/arm-template-expressions for usage details.'."}

Below is a copy of the template as generated by Azure:

What am I doing wrong? Whats the point of ARM templates if you cant export a working template from an existing resource group?

You problem lies here:

"subnet": {
     "id": "[resourceId('Microsoft.Network/virtualNetworks/subnets', parameters('subnets_Subnet_name'))]"
},

the error clearly states that

'resourceId': function requires exactly one multi-segmented argument which must be resource type including resource provider namespace. Current function arguments 'Microsoft.Network/virtualNetworks/subnets,vnet-myVnet/Subnet'.

So you must either redo your template to not include the subnet as separate resource, or create a variable that would extract proper vnet\subnet name from the parameters('subnets_Subnet_name') and pass each to the resourceId function, so it looks like this

"[resourceId(`Microsoft.Network/virtualNetworks/subnets, 'vnet-myVnet', 'Subnet')]"

add a variable like this:

variables: {
    ...
    "subnetSplit": "[split(parameters('subnets_subnet_name))]"
    ...
}

reference it like this:

"subnet" {
    "id": "[resourceId('Microsoft.Network/virtualNetworks/subnets', variables('subnetSplit')[0], variables('subnetSplit')[1])]"
}
