I am writing a script to quickly split large FCs and make them shareable. So I need the tool needs to know what the FC name is and What the Field Name is to split the FC into manageable segments.

To make the Field Name a dropdown would I need to have the user choose a FC and run the tool then have a second tool pop up with the Field Names available?

Set the 'Dependency' property for the field input parameter to be the table input parameter.

See the information under the 'Dependency' heading at: Setting Script Tool Parameters
