Hi Gibbon Team!  
I already reported a bug in “Administration” and saw that it would fit better here.

**Gibbon version:** v30.0.01  
**PHP version:** 8.3  
**OS:** AlmaLinux (production) / Debian via Docker (development)

**Description:**

In `src/Gibbon/Module/Reports/ReportSection.php`, the `addDataSources()` method contains a typo that causes report data sources to never be registered when passed as an array.

**Affected code (line ~51):**

php

```auto
public function addDataSources($sources)
{
    $sources = is_string($sources)
        ? json_decode($sources) ?? []
        : $source ?? []; // BUG: $source is undefined, should be $sources

```

When `$sources` is already an array (not a JSON string), the else branch uses the undefined variable `$source` instead of `$sources`. PHP silently returns NULL, so the foreach loop receives an empty array and no data sources are registered.

**Impact:**

Custom report card templates using Form Group scope (FormGroupCriteria data source) render completely empty - no grades, no student data. The template appears to load but produces a blank body section. The bug is masked because no PHP error is thrown for undefined variables in this context.

**Fix:**

Change line ~51 from:

php

```auto
: $source ?? [];

```

to:

php

```auto
: $sources ?? [];

```

**Environment:** Gibbon v30.0.01, PHP 8.3, AlmaLinux / Docker on Debian.

I hope this helps and let me know if this isn’t a bug or if you have any questions!
