## Operator.GetNumPortsInGroup

### Introduced

v3.0

### Description

Returns the number of Ports in a PortGroup. Returns -1 if there is a failure.

### C# Syntax

### Scripting Syntax

    oLong = Operator.GetNumPortsInGroup( PortGroupIndex );

### Return Value

Long

### Parameters

Parameter | Type | Description
--- | --- | ---
PortGroupIndex | Long | Port.GroupIndex

### Examples

#### JScript Example
