I'm a complete newbie to this. I'm trying to have a column show up based on two other selections in the form. So this is what I have based on one choice (after a LOT of googling):
=if([$Travel_x003f_] == 'Travel Required', && [$Transportation] == 'Fleet Vehicle Needed', 'true', 'false')
I need to show the column based on if Travel Required is selected, AND if either 'Fleet Vehicle Needed' OR 'Rental Car' is selected. How do I do that?
Try using this conditional formula:
=if([$Travel_x003f_] == 'Travel Required' && ([$Transportation] == 'Fleet Vehicle Needed' || [$Transportation] == 'Rental Car') , 'true', 'false')
Make sure you are using correct internal names of your columns. Follow this article to get the internal name of your columns: How to find the Internal name of columns in SharePoint Online?
