if_error

Evaluates value. If value returns an error, the function evaluates the alternative defined in error_value. Otherwise, the function returns value.

Note: This function is only available in Templates and can't be used in reporting.

Syntax

if_error(value, error_value)

Parameters

value and error_value can be an expression or one of the Search Ads 360 variables. They must both be of the same general data type which means that both the parameters must be either numbers, text or boolean.

You can nest this function to create an if, then or else evaluation.

Examples

• Converts a string to a number if the format matches the advertiser’s locale. Otherwise, returns 0:
  if_error(To_number("1.067,30"), 0)
• Returns “--” if there’s an error in the mid() function. Otherwise returns "Hello World!":
  if_error(mid("Hello World!", 0, 20), "--")
• Example of nested error checking. If there’s an error in the mid() function, the expression evaluates the left() function. If the left() function evaluates to an error, the expression returns “---”::
  if_error(
  mid("Hello World!", 0, 20),
      if_error(left("Hello World!", 5), “---”)
)
