How to increase a number by 1

I can seem to simply increase a number by one. When I use ADD, it ads another 1 to the existing 1 and makes 11. When I use SUM, it does the same thing.

How to I increase a number by one in appgyver???

Make sure your variable is a Number type and not a Text type.

I figured it out, just needed parenthesis. Thank you! I appreciate your taking the time to help.
