Storing incoming data from the serial port...having a tough time
in
Core Library Questions

I am using an Arduino with a cellular module as a "modem" for my computer. I send it data via txt message.
The code successfully recognizes incoming characters and takes action, however I need it to store the text message "text" in an array that I can use. The code does everything correct except generate the array. I have included the code, I have a hunch that it's something to do with either where/how the storeData function is called OR the for loop I use to store data. Please take a look! Thanks so much
