But first, let’s have some introductions about arrayformula, for those who has not used this before in Google Sheets, some equivalents in Glide and some good practices while using it. I hope it can help you in building your Glide apps as well as applying it in your normal day job. > > > **1/ Definition** > > > > Arrayformula is defined as “a range, mathematical expression using one cell range … > [@Majestic\_Intern](#): > > I previously had a use case where I wanted an auto increment column (1,2,3,4…) that would update every time a row is added, but never figured it out. If you ever need to do this again, here are a couple of methods that can be used with Glide Tables: > [@How do I create an auto-incrementing row number with Glide Tables?](https://community.glideapps.com/t/how-do-i-create-an-auto-incrementing-row-number-with-glide-tables/39572): > > This is a question that comes up a lot, so creating this topic to use as a reference. Typically, there are two distinct use cases when it comes to auto-incrementing row numbers. Use Case 1: – We need to generate a Part Number, or an Order Number, or an Employee ID. Once the number is generated, it should never change, even if rows are deleted. – The general approach for this use case is to maintain a static counter, use it to craft a suitably formatted ID, and increment it by one every time… > [@Majestic\_Intern](#): > > Collecting the form responses from Mighty Forms because it will be embedded on a website.

Also I’m using conditional logic on the form input, which would force me to make a custom form and entry field placeholders on glide.
