I am hoping to have this plugin track my KiLevel. The problem is that the mud has a prompt with commas in it.
(LifeForce:<86> Ki:<16,050>)


<triggers>
<trigger enabled="n" 
match="*(LifeForce:<*> Ki:<*>)*" 
group="prompt" 
ignore_case="y" 
script="trackKiLevel" 
sequence="100"/>
</triggers>

<!-- Aliases to set the alert level. -->

<aliases>
<alias enabled="y"
match="firstAlert *"
ignore_case="y" 
script="setFirstWarning"  
sequence="100"/>
</aliases>

<script>
<![CDATA[

require "tprint"
firstWarning = 0
currentKiLevel = 0

function setFirstWarning(name, list, args)
	firstWarning = args[1] + firstWarning -- sets the level to a number
	ColourNote("yellow","", "First Alert set to: ","cyan", "", firstWarning)
	EnableTriggerGroup("prompt", true)
end -- function

function trackKiLevel(name, list, args)
	currentKiLevel = tonumber(args[3]) + currentKiLevel
	ColourNote("yellow","", "Current Ki Level: ","cyan", "", currentKiLevel)
	if currentKiLevel < firstWarning then
		ColourNote("yellow","","WARNING! YOUR KI HAS DROPPED BELOW","","cyan", firstWarning)
	end -- if
end -- function
]]>
</script>

The error I get with it is:


Run-time error
Plugin: KiTracker (called from world: DB-Infinity)
Function/Sub: trackKiLevel called by trigger
Reason: processing trigger ""

You will need to get the comma out of that number (16,050).

For example:


  kilevel = string.gsub (args [3], ",", "")
  currentKiLevel = tonumber(kilevel) + currentKiLevel

Thank you, this worked. I was doing gsub wrong. Appreciate the quick response.
