Nested IF statements not working

[poggenpower]

PROBLEM DESCRIPTION

Nested IF Statements doesn't seems to work.
Following rule

ON Event#SetShutterBlock DO IF (%value% == 0) IF (%var3% != %var2%) Event ShutterMove=%var3% ENDIF;var1 %value% ELSEIF (%value% == 1) var1 %value% ELSE var1 0 ENDIF ENDON 

is not working as expected. The inner IF clause doesn't trigger the Event ShutterMove, here the log from the console:

17:11:12 RUL: EVENT#SETSHUTTERBLOCK performs "IF (0 == 0) IF (0.000 != 50.000) Event ShutterMove=0.000 ENDIF;var1 0 ELSEIF (0 == 1) var1 0 ELSE var1 0 ENDIF"
17:11:12 MQT: esp/esp03/stat/RESULT = {"If":"Done"}
17:11:12 MQT: esp/esp03/stat/RESULT = {"If":"Done"}
17:11:12 MQT: esp/esp03/stat/RESULT = {"Var1":"0"}

Simple IF clauses are working as expected.

TO REPRODUCE

Steps to reproduce the behavior:
Create rule like this:
ON Event#SetShutterBlock DO IF (%value% == 0) IF (%var3% != %var2%) Event ShutterMove=%var3% ENDIF;var1 %value% ELSEIF (%value% == 1) var1 %value% ELSE var1 0 ENDIF ENDON

Ensure you have set var2 and var3 to different values

trigger the rule via:
Event SetShutterBlock=0

EXPECTED BEHAVIOUR

A clear and concise description of what you expected to happen.
Event ShutterMove should get triggered if var2 =! var3
Means the inner IF clause gets evaluated and the should be executed.

SCREENSHOTS

If applicable, add screenshots to help explain your problem.
N/A

ADDITIONAL CONTEXT

Add any other context about the problem here.
From https://tasmota.github.io/docs/Rules/#conditional-rules

 1> <statement-list>
 2> - A Tasmota command (e.g.,LedPower on)
 3> - Another IF statement (IF ... ENDIF)
 4> - Multiple Tasmota commands or IF statements separated by ;. For example:
 5> Power1 off; LedPower on; IF (Mem1==0) Var1 Var1+1; Mem1 1 ENDIF; Delay 10; Power1 on
 6> Backlog is implied and is not required (saves rule set buffer space).
 7> 
 8> But not like this: Power1 off; LedPower on; IF (Mem1==0) Var1 Var1+1; Mem1 1 ENDIF; Delay 10; Power1 on
 9> 
10> You should split it in two lines like: ON Power2#state=1 DO Power1 off; LedPower on; ENDON ON 11> Power2#state=1 DO IF (Mem1==0) Var1 Var1+1; Mem1 1 ENDIF; Delay 10; Power1 on ENDON```

So in a `<statement-list>` another IF statement is allowed (line 3).
But some things are not clear to me: Line 5 and 8 gives the same rule, but one is wrong!?

[ascillato2]

Closing this issue as it is duplicated. Sorry.

This question has been answered before. Nested IF are not supported and will not be supported due to Flash and RAM restrictions. Please, rewrite your IF logic in the supported format.

If you need help on that, please address this to the Tasmota support chat. Thanks.

Remember to read the Contributing Guideline and Policy. Thanks.

@ascillato2
https://tasmota.github.io/docs/Rules/#conditional-rules says it is supported:

Syntax

IF statement supports 3 formats:

    IF (<logical-expression>) <statement-list> ENDIF
    IF (<logical-expression>) <statement-list> ELSE <statement-list> ENDIF
    IF (<logical-expression>) <statement-list> [ELSEIF (<logical-expression>) <statement-list> ] ELSE <statement-list> ENDIF
