List/Table in model builder

Discussion created by tatu on Jan 11, 2014
If someone could help get me started on the best approach to construct a model to do the following i would appreciate it greatly.

I need to have a drop down populated by values in a field  that will allow the user to select multiple values. For each value selected I want the user to be able to assign an attribute for that selection.. Example:

City   : Population
Jackson  : 100000
Orlando   : 500000

Where the city is selected from the drop down and the population is user entered. Much like the summary statistics tool that selects multiple fields and for each selected field you then select a statistic type.

The City results will be passed to the closest facility tool as Facility and the population value will later be used in a calculation.

Just some help getting pointed in the right direction would be great.
