Since Wesnoth 1.1.5, all simple substitution was eliminated in favor of complex substitution, which is more versatile.

There is no source for this claim, and my tests contradict it: In wesnoth 1.2.5, the WML snippet

			{VARIABLE foo_bar 42}
			{VARIABLE b bar}
			[gold]
				side=1
				amount=$foo_$b
			[/gold]

does nothing, but

			{VARIABLE foo_bar 42}
			{VARIABLE b bar}
			{VARIABLE_OP temp format $foo_$b}
			[gold]
				side=1
				amount=$temp
			[/gold]

adds 42 gold to side 1. I have therefore reverted the edit. Please only change the content of this page if you are sure you are right.

In the source file wesnoth-1.2.5/changelog, under the section for "Wesnoth 1.1.5", it states, "all [event] tags shall perform complex substitution".
Further, the following example passes wesnoth 1.2.5, and at least demonstrates that the [allow_recruit]type= key permits complex substitution:

# works in 1.2.5 [event] name=start {VARIABLE title "Sharpshooter"} {VARIABLE name title} [allow_recruit] type="Elvish $$name||" side=1 [/allow_recruit] [/event]

When I made a copy of 2p - Blitz with this event, side 1 was able to recruit Elvish Sharpshooters.
To show why your test failed, I suggest that "$foo_$b" is not a valid complex suggestion. (I do not know why "$foo_$b" does not work; maybe there is a bug in 1.2.5, or I misunderstand how complex substitution works.) The wiki page claims that [message]message= allows complex substitution, so I extended your example to be:

{VARIABLE foo_bar 42} {VARIABLE b bar} [gold] side=2 amount=$foo_$b # broken in 1.2.5 [/gold]

[message] speaker=narrator message=$foo_$b # broken in 1.2.5 [/message]

When I tested this, side 2 failed to gain 42 gold, and the message box can up with an empty message! --Kernigh 16:35, 15 July 2007 (CEST)
