I have a rollup column that shows a ( tasks done number). ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/7/b/7b421ba23ebb3a1b5d0f920cf47e51f68124f8c1.png) which is the count of a boolean checklist. ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/8/2/82df0b7267c618a45d0f5cb03c3566ff25dfa421.png) i want to compare this number if it reached 10 or any value from its multiples: 10 - 20 - 30 …etc. if yes then do some actions (set column values in different table)+ increments in different tables. if no then do nothing. how can i achieve this? i can add an if-else column and add each multiple by itself but i think there is a better way. how can i achieve this? thanks ---

Use a math column with a modulus formula: `Mod(Number,10)` If the math column returns 0, it meets your condition. ![CleanShot 2023-06-13 at 16.28.23@2x](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/6/4/6479f582420a2480d09400c675471e4732bd12fa.png) ---

Do you want to tie an action to the point where you click the 10th task then it would do something? I think you have to change things a bit to achieve that, because the “check” won’t give you an option to do another action. ---

thanks all for your replys. i had to change some logic in my app to work easier 😅. because its hard to do an action based off a check even in the future.
