functions may be used incompatibly or redefined

i am encountering problems such as:

1. the functions updatepopulation,trimr may be used incompatibly or redefined.
2. the values of xnew,ynew,fnew may not be used.

how should i solve these problems.

my code is as given below.

Show the full and exact text of any error (red text) or warning (orange text) messages you receive when you run this code. Don't trim or summarize the messages, copy them verbatim from the Command Window into a comment on this post. The error or warning messages will likely have information that will help in debugging the cause of the error or warning.

thank you for the response.. infact i do not get any error message while running the program. but the problem is i'm not getting the proper results. i am supposed to find a maximum value, but the code is not returning the maximum value. but on the 'message indicator', these errors are being shown.

You have two copies of the definition of trimr and updatepopulation

thank you!!
