Calculate Client Security Hash - Extract Work Items / Get Transaction Data

I’ve successfully extracted the Work Item data table & tested it (83 rows) and have variables & output argument as follows:

I’ve then invoked the required workflows in the Main Workflow (System1 Login, System1 Navigate to Work Item, System 1 Extract Work Item Data Table, System 1 Close) but I’ve done something wrong with my importing & binding arguments.

Any help would be much appreciated!
