Ok, apologies in advance for my ignorance. I am learning to code slowly. But I am new to Wix and have a great looking site building, but I don’t have the javascript knowledge to get my collections and user form data working the way I want them to. I have a lot of functions left to explore, but first and hopefully easiest is needing to understand how to write code to perform Excel-like calculations in columns. I can use formulas in Excel proficiently, so I want to use this type of thing in collections, but lack the language knowledge.
So here goes: How do I simply create a calculation to have the value of one column added or subtracted from the value of another column?
