I have python code that I want to turn into a script.
I want the end user to be able to navigate to the feature class the code should be run on.
The code I have currently speaks to a specific feature class and doesn't allow for picking what feature class the code is to be run on.
How do I change my code so I can have the parameters in the script allow the end user to pick what feature class the code should be run on?
This is the piece of code I need to change to allow the end user pick the feature class.. 
What do I need to change in my code to allow for the peramiters I set up in the script to replace this line of code? I need fc to equal the input the end user selects not a specific feature class as the code currently stands.
I changed that line of code to <SPAN class="pln" style="color: #000000;">fc </SPAN><SPAN class="pun" style="color: #000000;">=</SPAN><SPAN class="pln" style="color: #000000;"> arcpy</SPAN><SPAN class="pun" style="color: #000000;">.</SPAN><SPAN class="typ" style="color: #2b91af;">GetParameterAsText</SPAN><SPAN class="pun" style="color: #000000;">(</SPAN><SPAN class="lit" style="color: #800000;">0</SPAN><SPAN class="pun" style="color: #000000;">)</SPAN><SPAN class="pln" style="color: #000000;"> and set up parameters in my script dialogue but it errors out on me every time. Code works fine w/out the "getparametersastext" addition mentioned above.</SPAN>
