Help!! problems with "if sentences"

I have a <c:if test="${!empty UCD346 } "> sentences, but I having problems to handle just take a look to the code below

<c:if test="${!empty UCD346 } ">

<c:set var="ScanedBarcode" value="${'Barcode has been Scaned'}" scope="application" />

</c:if>

I don't know what happen, just this validation never get in to set my variable ="ScanedBarcode"

Probably there is sintaxis erro...
