I have an .aml script to set the tolerances that I always run on every coverage, I execute it through the ARC prompt but I see that it can be done through ArcToolbox by making it a script tool. I followed the on-line instructions and have created the dialog box, set the parameters to select the workspace and coverage. The script starts runs for about 5 minutes, it says it is complete but it does not set any tolerances. I'm not sure what I'm missing, any suggestions would be appreciated.
