Using DataDriver

Existing script design in *** Test Case ***
I need add changes to read data from excel file and then run execution for each row.
DataDriver design to run scripts from *** Keywords ***.
I try ad next: call from Test2.robot to Test1.log to read excel data -> collect all 10 arguments in Test1.log into list variables add pass it to existing file (Test2.robot)… execution is failed.
Error: Setting ‘Test Template’ is not allowed in resource file.
Is it possible to implement in this way or i need to modify existing script?
Is it possible to do next: read excel in Tes1.robot and run execution to Test2.robot after each line using [Tag] name on Tes2.robot?
I try to read loop, but Collection library from Robot Framework is not found. Do i need to install it separately?

Why are you not just call all steps you want to call in that keyword?
