[amibroker] What is wrong with these 3 lines of code?

[nunopires2001]

Hello,

After a encouraging start with Amibroker, i am realizing that writing
code on AFL is not all that simple...

Anyone can explain me what is wrong with these lines of code?

    CrossedIntermed=0;
    auxCrossedIntermed=IIf(Low< Intermed AND High> Intermed,1,0);
    CrossedIntermed=auxCrossedIntermed OR Ref(CrossedIntermed,-1);
    CrossedIntermed=IIf(TimeNum()>120000,666,CrossedIntermed);

I am working with intraday, 1min data. The market opens at 110000 and
closes at 193000.

I just want to check the CrossedIntermed Value after 12.00h, and the
value returned should be:
-> 1: If the security crossed Intermed
-> 0: Otherwise
-> 666: If TimeNum()>120000


Thanks alot!
