in reply to [SOLVED] possible to repeat if statement?

What you have implemented can be categorized as a "state machine", or "workflow".

More formal implementations of this are "data-driven", which means that each STATE and CONDITION combination drives you to either a new STATE or ACTION.
All this is defined in a single data-structure (or "rule" type file).

If you can restructure your program around this idea, it will become more stable, and extensible.
However- you pay the up-front cost in engine implementation, and having to consider every STATE/CONDITION combination.
There are several modules that can help - I don't have sufficient experience with them to advise. Search on the keywords "state machine", or "workflow".
