The Value does not contain 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 connected Event data Value where the second parameter, a string, should not be found.

By selecting Page URL as Value and "products" in Does not contain will restrict the Event to only trigger when the string "products" is not 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.
