Learning how to how to guess what the error messages mean and diagnose and correct mistakes in Mathematica code is an essential skill that you must somehow obtain.

Sometimes building up calculations one function at a time and checking to see the result is exactly what you expect before adding another layer of functions can help with this. Sometimes trying VERY simple test cases with data where you know what the answer should be can help with this. Unfortunately the error and warning messages, if you even get one, rarely clearly explain exactly what is wrong and why what you have done should be done differently.

Sometimes bits of your code change color if Mathematica thinks there is something wrong, but that is not GIANT BLINKING RED with an animated arrow bouncing up and down pointing at a mistake with a little thought bubble above it saying "What in the world do you think you are doing here?!? And why didn't you do THIS instead?!?!"

Using Zoom to magnify the whole sheet can sometimes make itty bitty errors, like ( instead of { and other such things, more visible.
