    <p>I've written a function and I wanted to return a variable from that function, but I keep getting an error</p> <p><em>local variable 'user' referenced before assignment</em></p> <p>My function is:</p> <pre><code> def txtelm(): # Updates date field to the current date if textElement.name == "DATE": textElement.text = strftime("%y %m %d") if textElement.name == "CHECK": textElement.text = "AB" # First code block replaces the "Drawn" title block initials if docauthor == "Mike" and textElement.name == "DRAWN": textElement.text = "MM" user = "mm" #print user elif docauthor == "Amy" and textElement.name == "DRAWN": textElement.text = "AB" user = "ab" #print user elif docauthor == "Ian" and textElement.name == "DRAWN": textElement.text = "IB" user = "ib" elif docauthor == "Chris" and textElement.name == "DRAWN": textElement.text = "CM" user = "cm" elif docauthor == "Cynthia" and textElement.name == "DRAWN": textElement.text = "CC" user = "cc" return user </code></pre> <p>Further down my code, I call the function:</p> <pre><code>for textElement in arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT"): txtelm() user = txtelm() if textElement.name == "PATH": textElement.text = outloc + "\\" + sitename.replace(" ", "_") + "_" + trunc + strftime("%d%b%y") + "_" + user </code></pre> <p>I set some print messages to print 'user', but it doesn't seem to be returning anything. Before I created the function I had the code within it, hardcoded below the 'for loop' and it worked....so I'm stumped as to why it's not returning any values.</p> <p>Any suggestions?</p>

    1. COmarginally easier to read text formatting: `textElement.text = os.path.join(outloc, "%s_%s%s_%s" % (sitename.replace(" ", "_"), trunc, strftime("%d%b%y"), user))`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
