<p>Is the label inside a table or grid bound to your data set and does the data set only return a single row? If so, you should be able to just check the row["yourfield"] value in the onCreate of the label and decide which value to show there.</p>
<p> </p>
<p>If the label is not in a table or grid bound to the data set, you could be sure to use separate run and render tasks and grab the value from the data element in the onCreate, store it in a PersistentGlobalVariable, and determine what to show in your label by grabbing this PGV in the onRender of the label and setting the text.</p>
<p> </p>
<p>If you're not using separate run and render and the label is not in a table or grid bound to the data set, you could likely just use a dynamic text element bound to the data set that the data element is bound to and write an expression checking the data value to determine the label value.</p>

<p>Hope one of these helps.</p>
