You have misinterpreted the documentation slightly. It says the returned results are:



The contents of the specified trigger wildcard, as described above.



An EMPTY variant, if the trigger does not exist.

A NULL variant if the trigger name is invalid.

An empty string if the wildcard does not exist.

An empty variant is something you test with "IsEmpty" - that is returned if the trigger does not exist. However your trigger does exist.

An empty string is what is returned if the wildcard does not exist. An empty string is this: "".

So your code should read like this:


if gain <> "" then
  ColourNote "white", "red", gain
end if

I have amended the documentation for GetTriggerWildcard to make that a bit clearer.

You can test this sort of thing yourself. I did this:


Note (VarType (GetTriggerWildcard ("mytrigger", 1)))
Note (VarType (GetTriggerWildcard ("mytrigger", 8)))

It was clear from the results (8 and 8) that I was getting a string result, however in the second case the string was an empty string.

See the VBscript documentation for the meaning of VarType:


vbEmpty     0 Empty (uninitialized) 
vbNull      1 Null (no valid data) 
vbInteger   2 Integer 
vbLong      3 Long integer 
vbSingle    4 Single-precision floating-point number 
vbDouble    5 Double-precision floating-point number 
vbCurrency  6 Currency 
vbDate      7 Date 
vbString    8 String 
vbObject    9 Automation object 
vbError    10 Error 
vbBoolean  11 Boolean 
vbVariant  12 Variant (used only with arrays of Variants)

Thanks a bunch Nick, I greatly appreciate it.

I can't even tell you how frustrated I was. I'm glad you noticed that I was misunderstanding what it meant. Cause I had no idea.

But It's working perfectly now.

Final Trigger:

<triggers>
  <trigger
   enabled="y"
   expand_variables="y"
   keep_evaluating="y"
   match="^\&lt;(.*?)\%\&gt; \/ \&lt;(.*?)/(.*?)\&gt;(( vs. \&lt;(.*)\&gt;)?| (\+(.*) Max Powerlevel)?)$"
   name="Prompt"
   regexp="y"
   repeat="y"
   send_to="12"
  >
  <send>maxpl = GetTriggerWildcard ("Prompt", 3)
form = "@Form"
SetVariable "MaxPowerLevel", maxpl
if form = "Super Saiyan" then
expectedgain = Int((maxpl / 2) * .05)
elseif form = "Super Saiyan 2" then
expectedgain = Int((maxpl / 3) * .05)
elseif form = "Super Saiyan 3" then
expectedgain = Int((maxpl / 4) * .05)
elseif form = "Ultimate Super Saiyan" then
expectedgain = Int((maxpl / 2) * .05)
elseif form = "2" then
expectedgain = Int((maxpl / 1.25) * .05)
elseif form = "3" then
expectedgain = Int((maxpl / 1.75) * .05)
elseif form = "4" then
expectedgain = Int((maxpl / 2.625) * .05)
else
expectedgain = Int(maxpl * .05)
end if

sleep = GetVariable("Sleep")
gain = GetTriggerWildcard ("Prompt" , 8)

if sleep = "sleeping" then
if gain &lt;&gt; "" then
gamesessiongain = Int(GetVariable("GameSessionGain")) + gain
powerlevelgain = Int(GetVariable("PowerLevelGained")) + gain
SetVariable "PowerLevelGained", FormatNumber(powerlevelgain,0,0,0,-1)
SetVariable "GameSessionGain", FormatNumber(gamesessiongain,0,0,0,-1)
Note "Current gain is: +" &amp; FormatNumber(powerlevelgain,0,0,0,-1)
end if
end if
SetVariable "Expectedgain", expectedgain</send>
  </trigger>
</triggers>

Works like a charm with a few other triggers I have.
