Yes, there will be a different way to code multiple deletes. I chose, for convenience, to simply loop through the pre-existing single delete as many times as necessary rather than write a new function. I’m sure this will be the cause of the problem.
What is needed is a completely different function for deleting that allows for multiple deletes. I will look at this when time permits. Meanwhile I would definitely recommend you use a more convenient browser if you know you will need to perform multiple deletes.
