Hi Ruby…

I have an SNMP command that I’m using which works fine in my script:

There is a static portion that needs to be changed so I can feed in the  
variable and it’s a bit tricky. I have tried every combination of " "  
and ’ ’ that I can think of and nothing works.  
Here is the line of code that works:

```
   response = m.get (["ifInOctets.1"])

```

The number “1” in the above piece of code needs to be changed to a  
variable.

Any ideas on how to squeeze a variable in there?

thanks

Use string interpolation:

response = m.get(["ifInOctets.#{number}])
