Looking to create a lookup workflow that can filter multiple items against database

Question

I am needing some assistance in creating a workflow that I can drop open item numbers as a filter and grab those open item numbers only against a master database. I am having trouble making this work, any ideas on a better way of keeping a workflow that can allow a filter to select open item numbers such as the attached workflow I am trying to build from?

Dynamic Filter.yxzp

You can use a Select Tool to change the data type.
