MA Cross - ***Programmers*** Please help with alertcondition()

Hello Traders and coders,

Here is a fundamental version of a moving average cross trading strategy that works on 1H and 4H timeframes.

It's very simple and would be well paired with proper technical analysis and risk management.

I am looking to use this to alert me of potential setups. I could not get the alertcondition function to work properly. If anyone can help me with that please comment or message me.
