| I am trying to capture a name from a trigger and then decide which action to take based on the name. The trigger match is the following:
^(.*?)The black stone guides(.*?)into gaining level (.*?)\!$
my attempt at a script is the following:
SetVariable ("lasttolevel", %2)
local justleveled = GetVariable ("lasttolevel")
if justleveled == "Burzmali" then
SetVariable ("clevel", %3)
else
Send ("say keep on truckin justleveled. Gratz!")
end
I am hoping the value of justleveled will be output by the say command not "justleveled" but i haven't got that far yet. I am getting the error:
[string "Trigger: "]:1: bad argument #2 to 'SetVariable' (string expected, got nil)
stack traceback:
[C]: in function 'SetVariable'
[string "Trigger: "]:1: in main chunk
what am i missing?

| Say Nick just levelled. That line will then read:
SetVariable ("lasttolevel", Nick)
However the variable Nick is nil. You really want to quote it:
SetVariable ("lasttolevel", "%2")
And further on you want:
Send ("say keep on truckin " .. justleveled .. ". Gratz!")
That concatenates a variable with some literal strings.

| Thanks again. I actually managed to get the first part figured out but the ability to combine strings and variables had eluded me.
