Display modified Switch number

[Nazar]

Hi All!

I have downloaded and modified template for Juniper QFX and have some problems
The problem is about displaying some items. After zabbiz has been collected some data, I can see the result like this:

Switch 1 - 5 min load average
Switch 1 - CPU usage
Switch 1 - Memory usage
Switch 1 - Routing Engine temperature
Switch 2 - 5 min load average
Switch 2 - CPU usage
Switch 2 - Memory usage
Switch 2 - Routing Engine temperature

But in Juniper nodes start numbering from 0, not from 1. So it's good idea to keep
Node 0
Node 1

Actually there no problem to change "Switch" to "Node" word, but the problem is I don't know how to decrease number by 1 in my case. For example
<name>Switch {#SNMPVALUE} - CPU usage</name>

I have tried something like this:
{#SNMPVALUE-1}
[{#SNMPVALUE}-1]
({#SNMPVALUE}-1)
But no success.

Is there some way to do it?
