Unable to update the worklow default selection through the interface tool

[radhikasood1112]

I created an app and I want the user to enter the zipcode by DMA. This selection should be passed on to the underlying Allocate input tool. This should trigger the workflow. I have to keep one selection (one zipcode must be selected) in the allocate input tool (otherwise it throws an error). can you please provide help that the user selection(from the interface tool) should update the default selection in the allocate input tool. Thanks in advance.

Hi @radhikasood1112 

Tree tool doesnt have default option setting. Why not use list box or drop down? Why are you using tree tool?

I resolved it by using the Update RAW XML with Formula, and update the Outer XML. Thanks atcodedog05 for the. help.
