Using Parentheses

When programming in VBScript, it is important that you follow the rules for using or not using parentheses () in your statements.

You must use parentheses around method arguments if you are calling a method that returns a value and you are using the return value. For example, use parentheses around method arguments if you are returning a value to a variable, if you are using the method in an If statement, or if you are using the Call keyword to call an action. You also need to add parentheses around the name of a checkpoint if you want to retrieve its return value.

Tip: If you receive an Expected end of statement error message when running a step in your test, it may indicate that you need to add parentheses around the arguments of the step's method.

The following examples show when to use or not use parentheses.

Returning values to a variable

The following example requires parentheses around method arguments, since it returns a value to a variable:

Set WebEditObj = Browser("Mercury Tours").Page("Method of Payment").WebTable("FirstName").ChildItem (8, 2, "WebEdit", 0)

WebEditObj.Set "Example"

Call usage

The following example requires parentheses around method arguments, since Call is being used:

Call RunAction("BookFlight", oneIteration)

Back to top

If statements

The following example requires parentheses around method arguments, since the method is used in an If statement:

If Browser("index").Page("index").Link("All kind of").WaitProperty("attribute/readyState", "complete", 4) Then Browser("index").Page("index").Link("All kind of").Click

Checkpoint values

The following example requires parentheses around method arguments, since it returns the value of the checkpoint:

a = Browser("MyBrowser").Page("MyPage").Check (CheckPoint("MyProperty"))

Back to top

No value returned

The following example does not require parentheses around the Click method arguments, since it does not return a value:

Browser("Mercury Tours").Page("Method of Payment").WebTable("FirstName").Click 3,4
