Validation based on equation

I have two multiple choice questions Q1 and Q2.
For each of them I have more than 20 checkboxes.
Each checkbox of Q1 has a score of 3 (in my mind) and every checkbox of Q2 has a score of 6.

I need the final score to be exactly 51 (sum of 3*number of checks in Q1 + 6*number of checks in Q2). So I set up an equation question with the expression:
{9+count(that.Moduli3)*3+count(that.Moduli6)*6}

Would you guide me in the process of setting a condition such that if the score of equation is not exactly 51 the survey will not proceed?

I tried read forums and the manual, but still is not clear to me how to do.
I'm new to LimeSurvey so I will really appreciate your help!
Thanks a lot!

Assuming question codes "Q1" and Q2" and both questions are on the same screen, something like this in the Question validation equation for both questions:
sum(count(that.Q1)*3, count(that.Q2)*6) == 51

And, this for the Question validation tip:
{if(sum(count(that.Q1)*3, count(that.Q2)*6) == 51, 'Okay to proceed', 'Cannot proceed')}

If the questions are on separate pages, place those in Q2 only.

Thanks a lot!
It works if I test the survey you sent, but it doesn't if I put it on my survey...
The prompt and the numbers selected are shown correctly. However, with the correct score I cannot proceed...

Can you help me figure out why?

Thanks again

You have relevance on those questions which may mess things up but try adding .NAOK:

sum(count(that.Moduli3.NAOK)*3, count(that.Moduli6.NAOK)*6) == 51

And:

{if(sum(count(that.Moduli3.NAOK)*3, count(that.Moduli6.NAOK)*6) == 51, 'Numero crediti corretto', 'Numero crediti errato')}

Thanks. This doesn't change things, but thanks to your answer I noticed that the relevance equation got automatically transformed into something strange.

This was the relevance equation I originally set up:
((BorsaINPS.NAOK != "1") and (GiaSottomesso.NAOK == "N") and (Dottorandi.NAOK == "N") and (SoloOnline.NAOK == "N"))
Then for some question it was automatically changed into:
((565358X8X136.NAOK != "1") and (565358X8X138.NAOK == "N") and (565358X8X139.NAOK == "N") and (565358X8X140.NAOK == "N"))

Having fixed that, now everything works!
I don't know if this is the place, but perhaps the automatic change is a bug we can signal.

The strange something is the SQGA identifier.
