This template formats a single line for a Mermaid graph.
* '''{{{1}}}''' should be the source page (subject).
* '''{{{2}}}''' should be the destination page (object).
It creates a line like: Concept:Node_A["Node A"] --> Concept:Node_B["Node B"]
</noinclude>
```**Explanation of the fix:**
*  This template now requires two parameters, `{{{1}}}` (the source) and `{{{2}}}` (the destination).
*  `{{PAGENAMEE:...}}` creates a valid ID for Mermaid (e.g., `Concept:Node_A`).
*  `{{#titleparts:...|2}}` creates a clean label for the node, stripping the "Concept:" prefix (e.g., `Node A`).

### Step 2: Fix the Graph Page Query
 
Now, we'll update the query to feed the corrected template the two parameters it now expects.
 
**Edit Page:** `Project:Mermaid_Graph_Test`
 
**Replace the entire content of the page with this:**
 
```wikitext
This page tests the dynamic generation of a Mermaid graph from Semantic MediaWiki data.
 
{{#mermaid:
graph TD;
{{#ask:
