I am trying to use arctoolbox and python so that the user can enter in parameters. In my script I have the following lines

_StationInterval = arcpy.GetParameterAsText(0)

I just want the user to be able to enter in a value for the station interval. However I get the error:

<type 'exceptions.NameError'>: name '_StationInterval' is not defined
Failed to execute (Final3Test).

Before I used arctoolbox, I had the station interval set to a value in the script, i.e. _StationInterval = 10000

Am I missing something in my script??

Post the rest of your script so we can see what else is going on... –  Jason Mar 8 '13 at 21:36
    
does the error occurring at the line you posted? –  Emi Mar 9 '13 at 3:16
    
Uhm,...I think so. I mean, the arc toolbox doesn't tell me a line of where the error occurred –  user1898629 Mar 11 '13 at 15:14

Your script is probably fine but it sounds like you have not defined a Parameter for it on the Properties of your Python script tool.

The process for doing that is described here.

I have already defined and set the parameters within the properties box of arctoolbox. I'm still getting the same error. Is there some snippet of code I need to include in actual python script (other than what I've posted above) to define the parameters as well? –  user1898629 Mar 11 '13 at 17:47
    
If you have defined a function within your Python script and the variable is set outside of it then you may have a scoping issue. If that is the issue just pass it in as a parameter to the function. –  PolyGeo Mar 11 '13 at 22:29
