Ich mache die Lektion Predict floods with unit hydrographs | Learn ArcGIS und im Abschnitt "Create a Unit Hydrograph: Prepare the Unit Hydrograph Table," Nr. 13, erhalte ich diesen Fehler: FEHLER 002717: Ungültiger Arcade-Ausdruck, Arcade-Fehler: Semikolon oder neue Zeile erwartet, Skriptzeile: 1 Ausführung von (CalculateField) fehlgeschlagen. Ist etwas falsch mit dem Code !Count! * 30 * 30? Danke, Erica

Hi Erica Price David is correct. This is an error in the lesson: For Arcade you should use: $feature [ "Count" ] * 30 * 30 // or $feature . Count * 30 * 30 You can also change it to Python and use the formula mentioned in the lesson: !Count! * 30 * 30

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

Gibt es einen Fehler in dieser Lektion?

Hi Erica Price

David is correct. This is an error in the lesson:

For Arcade you should use:

$feature<SPAN class="punctuation token">[</SPAN><SPAN class="string token">"Count"</SPAN><SPAN class="punctuation token">]</SPAN> <SPAN class="operator token">*</SPAN> <SPAN class="number token">30</SPAN> <SPAN class="operator token">*</SPAN> <SPAN class="number token">30</SPAN>
<SPAN class="comment token">// or</SPAN>
$feature<SPAN class="punctuation token">.</SPAN>Count <SPAN class="operator token">*</SPAN> <SPAN class="number token">30</SPAN> <SPAN class="operator token">*</SPAN> <SPAN class="number token">30</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

You can also change it to Python and use the formula mentioned in the lesson:

!Count! <SPAN class="operator token">*</SPAN> <SPAN class="number token">30</SPAN> <SPAN class="operator token">*</SPAN> <SPAN class="number token">30</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

Looks like Python Field Calculator syntax?

I don't use Arcade unfortunately, but the documentation suggests a syntax like:

$feature["fieldname"] * 30 * 30
