It is not a good idea to post screenshots of code. Please copy and paste the actual code and errors. Use the 101010 button to highlight and format the code.

You can't pass wild card files to trimmomatic. If you have more than one sample then run the trimming for each set of sample via a for loop.

You are passing too many files into the tool, it runs out the fields that it considers inputs/outputs and starts treating a file name as a trimming action.

Read up on the tool and adjust your inputs.
