Error with using the Join Field Management tool

Discussion created by ekaterinafitos on Sep 18, 2011
For ArcGIS 10 SP2 (using the ArcInfo license and Spatial Analyst extension), I am attempting to use the join field tool between a shapefile and a file geodatabase feature class.  However, the script is performing erratically where it works for some machines adding the field and values while other times it only calculates the field with one value (in the screen capture below refer to ElementZ_1) when it should be multiple values as it is correcting the ElementZ value.  It is using the x coordinate field as the joining field.  The script is below.  It is a pretty straight forward script.  The original data is coming from an ArcPAD generated shapefile.  Are there any known issues with the join field tool or any ideas as to what can be causing this issue? 

Thanks for your help.

Regards,

Kathy
