Yoichi,
I figured it out.
The whole time, it was set to “do” (circled area) - setting it to sequence solved my issue.
You were of great help, however, in confirming that you don’t need 2 separate elements being incremented, just one.
I used:
<html app='firefox.exe' title='Company CCC Application - Financial Model' />
<webctrl id='tblEquipment' tag='TABLE' />
<webctrl id='supplierProdId{{Counter}}' tag='INPUT' />
Thank you so much -
