The Value contains condition will let you restrict an Event based on a connected Event Data. You will have to specify two parameters in order for the condition to work.

First parameter is the string that should be found in the second parameter that is a connected Event data value.

By specifying "products" in Should be contained and selecting Page URL as In Event Data will restrict the Event to only trigger when the string "products" can be found in the current URL.

Note that this condition must always be wired to an Event Data before you can select it as a parameter.

The condition is case-insensitive.
