In RobotFramework, is it possible to run test cases in For-Loop?

So my issues might be of syntactic nature, maybe not, but I am clueless on how to proceed next. I am writing a test case on the Robot Framework, and my end goal is to be able to run ,multiple tests, back to back in a Loop.

In this cases below, the Log to Console call works fine, and outputs the different values passed as parameters. The next call "Query Database And Analyse Data" works as well.

*** Test Cases ***
| For-Loop-Elements
| | @{Items} =                    | Create List | ${120} | ${240} | ${240} 
| | :FOR                          | ${ELEMENT} | IN | @{ITEMS}
| | | Log To Console              | Running tests at Voltage: ${ELEMENT}
| | | Query Database And Analyse Data

But then, when I try to makes a test cases with documentation and tags with "Query Database And Analyse Data", I get the Error: Keyword Name cannot be Empty, which leads me to think that when the file gets to [Documentation tag], it doesn't understand that it is part of a test case. This is usually how I write test cases.

Please note here that the indentation tries to match the inside of the loop 

*** Test Cases ***
| For-Loop-Elements
| | @{Items} =                    | Create List | ${120} | ${240} | ${240} 
| | :FOR                          | ${ELEMENT} | IN | @{ITEMS}
| | | Log To Console              | Running tests at Voltage: ${ELEMENT}

| | | Query Database And Analyse Data
| | | | [Documentation]           | Query DB.
| | | | [Tags]                    | query | voltagevariation

| | | Duplicates Test
| | | | [Documentation]           | Packets should be unique.
| | | | [Tags]                    | packet_duplicates | system
| | | | Duplicates

| | | Chroma Output ON
| | | | [Documentation]           | Setting output terminal status to ON
| | | | [Tags]                    | set_output_on | voltagevariation
| | | | ${chroma-status} =        | Chroma Output On | ${HOST} | ${PORT}

Now is this a syntax problem, indentation issue, or is it just plain impossible to do what I'm trying to do? If you have written similar cases, but in a different manner, please let me know!

Any help or input would be highly appreciated!

You are trying to use Keywords as Test Cases. This approach is not supported by Robot Framework. What you could do is make one Test Case with a lot of Keywords:

*** Test Cases ***
| For-Loop-Elements
| | @{Items} =                    | Create List | ${120} | ${240} | ${240} 
| | :FOR                          | ${ELEMENT} | IN | @{ITEMS}
| | | Log To Console              | Running tests at Voltage: ${ELEMENT}
| | | Query Database And Analyse Data
| | | Duplicates
| | | ${chroma-status} =        | Chroma Output On | ${HOST} | ${PORT}

*** Keywords ***
| Query Database And Analyse Data
| | Do something
| | Do something else
...

You can't really fit [Tags] anywhere useful. You can, however, fire meaningful fail messages (substituting the [Documentation]) if instead of using a Keyword directly you wrapped it in Run Keyword And Return Status.

Furthermore, please have a look at data driven tests to get rid of the :FOR-loop completely.
