I have two images that I want to display according to a value from the dataset/dynamic text in the report. I am getting errors when trying to do it.

if(this.getRowData().getExpressionValue("row[price]") == "$30" )
this.imageName = "check.JPG";
else
this.imageName = "unchecked.JPG";
The error:

org.eclipse.birt.report.engine.api.EngineException: There are errors evaluating script "if(this.getRowData().getExpressionValue("row[price]") == "$30" ) this.imageName = "check.JPG"; else this.imageName = "unchecked.JPG";": TypeError: Cannot call method "getExpressionValue" of null (/report/body/image[@id="84"]/method[@name="onCreate"]#1)

The error you are getting is because you have null values in your dataset. You should check for nulls in your if statement first, then check for your price.
