I am trying to create a if else statement that if the label value is equals to 0 zero it will failed the step but my code has an error on that part.  
Here’s my code:  
import com.kms.katalon.core.checkpoint.Checkpoint as Checkpoint  
import com.kms.katalon.core.cucumber.keyword.CucumberBuiltinKeywords as CucumberKW  
import com.kms.katalon.core.mobile.keyword.MobileBuiltInKeywords as Mobile  
import com.kms.katalon.core.model.FailureHandling as FailureHandling  
import com.kms.katalon.core.testcase.TestCase as TestCase  
import com.kms.katalon.core.testdata.TestData as TestData  
import com.kms.katalon.core.testng.keyword.TestNGBuiltinKeywords as TestNGKW  
import com.kms.katalon.core.testobject.TestObject as TestObject  
import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS  
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI  
import com.kms.katalon.core.windows.keyword.WindowsBuiltinKeywords as Windows  
import internal.GlobalVariable as GlobalVariable  
import org.openqa.selenium.Keys as Keys

import static com.kms.katalon.core.testdata.TestDataFactory.findTestData  
import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject  
import static com.kms.katalon.core.testobject.ObjectRepository.findWindowsObject  
import java.nio.file.Path as Path  
import java.nio.file.Paths as Paths  
import com.kms.katalon.core.testobject.ConditionType as ConditionType  
import org.apache.commons.lang3.StringUtils as StringUtils  
import com.kms.katalon.core.util.KeywordUtil as KeywordUtil

string (Failure = WebUI.getText(findTestObject(‘Admin/WP-0010 Container with Failures count and Its Listings/Page\_Dashboard/label\_4’),  
FailureHandling.CONTINUE\_ON\_FAILURE))

if (Failure == 0) {  
KeywordUtil.markFailedAndStop(‘Test has unexpected value. Failure=’ + Failure)  
} else {  
Condition here  
}

Is there wrong with my condition or if there is another import file should I get? Thank you for any help.

Zero as in 0, is an Integer. However, “0” or ‘0’ is zero as a String (note the **quotes** around the zero). You can also have, 0.toString().

So, your statement,  
`if (Failure == 0) {`  
is trying to compare a String to an Integer, which should always fail\*. Choose one of the options that I gave and try again.

Your error message, “groovy.lang.MissingMethodException:” usually means that you do not have the correct **data type** for your parameters or the correct **number of parameters** for your method.

If I read correctly, you are trying to get an error number from your browser’s, “label\_4”. Is that correct? Just remember that the “getText()” method returns a **String** , never an Integer, even if it looks like a number.

Edit: And, I noticed you have parenthesis around your expression:

```auto
string (Failure = WebUI.getText(findTestObject(‘Admin/WP-0010 Container with Failures count and Its Listings/Page_Dashboard/label_4’), FailureHandling.CONTINUE_ON_FAILURE))

```

Remove the parenthesis in the above statement, so it becomes:

```auto
String failure = WebUI.getText(findTestObject('Admin/WP-0010 Container with Failures count and Its Listings/Page_Dashboard/label_4'), FailureHandling.CONTINUE_ON_FAILURE)

```

This might be the cause of your “groovy.lang.MissingMethodException:”.

This could work for you…

```auto
//You would first get the string value
//Then convert the string to an int
//Then use the if statement...

String Failure = '0'
//String Failure = WebUI.getText(findTestObject('Object'), FailureHandling.CONTINUE_ON_FAILURE)
int FailureValue = Failure.toInteger()
if (FailureValue == 0) {
	println('FailureValue == 0') 
} else {
	println('FailureValue != 0')
}

```
