New on AAO and already lost with LVAR and TTS

[davierosoft 13]

Hi all! I'm a new buyer of AAO and I already tried to study the manual and to do a script with the editor. However it is always "red" and I really don't know if I'm doing correctly.
I want to add some TTS voices to be activated with the mission system of the hype h145 helicopter. The mission script may create LVARS and assign them the value I want.
I want to use a single or multiple LVARS to trigger a TTS voice however it seems I'm losing something as when I enter (L:VARIABLE_BLABLABLA, number) the red light is there and giving me the error for the entire command. If I try to put the == if and so on, I always have the red light so for sure I'm doing wrong but I'm lost...

I have also a question: If I want to use a single LVAR to trigger let's say 10 different phrases, not in a specific order, and only when the variable is set to it, do I need to put a repetition or goto or something? Or it will continue to run the script?

It would really help if you post your acutal code. It is hard to say what you are doing wrong when we cannot see what it is that you are doing
