I am getting a error if i have an prompt input value as "integer" but i was able to run the report if the input is "string". I am getting the following error:

Error: RuntimeContext.ERROR_0018 - The requested parameter "Value" has a NULL value (org.pentaho.core.runtime.RuntimeContext)

Error: RuntimeContext.ERROR_0013 - Parameters could not be resolved (org.pentaho.core.runtime.RuntimeContext)
Error: SolutionEngine.ERROR_0007 - Action sequence execution failed (org.pentaho.core.solution.SolutionEngine)

Can anyone help me....

Thanks in advance
