The description of a sequence diagram is harder than other kind of representations as there are more parameters to set, so for a beginner I would recommand to start with another kind of representation in order to start modeling with Sirius with easier steps.
Anyway, from your screenshot, I can tell you that on your Basic Message description, there is an issue with your semantic candidate expression. This expression is executed from the current element (here the semantic element used to create your diagram) and is expected to return a set of candidate elements (to display as message). On the screenshot, we can see that it is filled with a String label.
Also, your creation message has the same issue, but there is also a typo in the target finder expression as it is filled with "...recereceivingEndFinder".
I think that it will be easier for you to look how some examples of Sequence diagram are done. You can either look into UML Designer, it is open-source.
There is another sample in Sirius that is available in git . It is the Interaction modeler and you will need the four plugins starting with "org.eclipse.sirius.sample.interactions".
