Thank you for taking a moment to read my request for help. It has been a few years since I have worked in creator, so please be patient. 

I have a form named Build_Sheet where several values are entered during an assembly process. Such as serial numbers, configurations etc. 

I have a second form named Data_Collection where additional information is stored about the equipment in the Build_Sheet form.

Workflow is as follows. 

1. Assembly builds a new tool comprised of multiple serialized components, and enters the configuration into Build_Sheet form
2. Operations deploys tool in a work environment.
3. Operations opens the Data_Collection form and selects a value in a lookup dropdown that pulls the value Build_Number from the Build_Sheet form.
4. Operations enters environmental data from that work environment into the Data_Collection form. 

Question two, if I may be so bold.
How can I concatenate the values from two fields into a third field as the form is being populated by the user. 

Field 1. Asset_Id#

Field 2. Date picker

Desired Field 3. XXXXX-MM.DD.YYYY

There is some redaction in the screen shots I hope this does not make it to confusing. Thank you again for your insight.
