Topic: scripting help.. unexpected behavior
So I'm working on a modified MIDI Fighter Twister mapping where if you press the encoder it either kills (0) or resets a STEM (0.5)

($enc_buffer is set to 0.03, the idea is that if you have the stem low you probably don't want it to go lower but reset to normal. enc_buffer determins how close to low you can be)

My issue is that when I run this action it works for going from no stem (0) to full, but not in reverse

Relevant code parts:
	
<map value="MD1_ENC_1_1" action="deck 3 stem Vocal    " />
<map value="MD1_PUSH_1_1" action="var_smaller  `deck 3 stem Vocal`    $enc_buffer ? deck 3 stem Vocal   0.5 : deck 3 stem Vocal   0   "/>


Interestingly, what does work is this:

	<map value="MD1_ENC_1_1" action="deck 3 stem Vocal   & set_var $md1_1_1 `deck 3 stem Vocal  `  " />
	<map value="MD1_PUSH_1_1" action=" var_smaller $md1_1_1 $enc_buffer ? deck 3 stem Vocal   0.5 & set_var $md1_1_1 0.5 : deck 3 stem Vocal   0 & set_var $md1_1_1 0  "/>


The only difference I can tell is the addition of the variable in the second. I'm sure I'm doing something wrong I just don't see it

you have params wrong way round for the verb, valid version
var_smaller VARNAME `ACTION`
var_smaller `ACTION` `ACTION`

So for my example, i would need to to this: (?) 

<map value="MD1_PUSH_1_1" action="var_smaller  $enc_buffer `deck 3 stem Vocal`  ? deck 3 stem Vocal   0.5 : deck 3 stem Vocal   0   "/>


That did not work.

This also did not work:

<map value="MD1_PUSH_1_1" action="var_smaller `$enc_buffer` `deck 3 stem Vocal`  ? deck 3 stem Vocal   0.5 : deck 3 stem Vocal   0   "/>
