How to print custom message in failure handling

Thanks once gain Melocik. I also derived another way from your hint. Which is very much similar to your work.

if(WebUI.verifyElementClickable(findTestObject(‘abc/button_next1’), FailureHandling.OPTIONAL))
{
WebUI.click(findTestObject(‘abc/button_next’), FailureHandling.OPTIONAL)
log.logInfo(" abc " + PageName[i])

	}
	else
	{
		KeywordUtil.markFailedAndStop(" abc "  + PageName[i])
	}
