For testing purposes, change your next button to show when only one of the buttons is clicked. If it works for just one, then add the second button, etc. so you can figure out where the code is breaking.This might be a bit simplistic but I'd recommend dealing with one variable per button. It makes the next button a bit clunky but it helps with troubleshooting. Have the next button show when button1=1; button2=1; button3=1, etc. Others probably have some better ideas on how to handle this but going the simple route with variables seems to work best for me.If none of the above work then it might be a refresh problem where your page needs to be refreshed to show the change in variables. It sounds like this is not the case, though, as you're coming back to the page from somewhere else. Build a separate page somewhere for testing purposes that displays the variable values. This will help you see what the variable is doing as you're working.
