Coding Help Starting and Ending with a certain Character

No, those are not helping. Example 3 doesn't parse the data and the example that does parses it and puts the parsed data into a message that displays an integer, character and a float.

My code as it is, if i call it like <100,2,3,4,5,6 the serial monitor prints

100
2
3
4
5
6

If i close the input with > the code doesnt work.
