Here is my code, from the search results page:
{if $listing.SalaryType!=''&& $listing.Salary!=''}<dt>Salary:</dt>
<dd>{$listing.Salary} {$listing.SalaryType}</dd>{/if}
Which gives this output:

It says 'Array' instead of the correct value. Any idea where I can start looking to solve this problem? Where is the 'Array' coming from?
Here is some more information. On the job details page, this code:
<div class="smallListingInfo"><strong>[[FormFieldCaptions!Salary]]:</strong> {display property=Salary} [[$listing.SalaryType]]</div>
Gives this output:

You can see the salary value works in this instance, how is that different?
Using the smarty debug console I got the following:
Title => Services Senior Manager
EmploymentType => Contractor
JobCategory => Accounting,Admin-Clerical
Occupations => empty
Country => United States
Salary => Array (5)
add_parameter => 2
value => 30000
currency_sign => £
course => 1
currency_code => USD
State => California
SalaryType => per month
City => Los Angeles
How do I get the value to show instead of 'Array'?
