Question

I am trying to make a "Curve of Forgetting" study planner, with a date that is automated to change as I check off a day of studying.

The table included checkpoints of 5 Mins, 30 Mins, Day 1, Day 4, Day 7, Day 15, and Day 30.

To try and explain the problem better, I am trying to get the "Due Date" property to change based on which boxes I have checked off. For example, if I have checked off the 5 Mins and 30 Mins boxes, the date would automate to 1 day after the "Day 0" property, and on and so forth for all of the listed dates.

Here is my code:

if(prop("5 Mins"),formatDate(dateAdd(prop("Day 0"), 25, "minutes"),"MMMM D, Y H:mm A"),formatDate(prop("Day 0"), "MMMM D,Y H:mm A")), if(prop("5 Mins")&&prop("30 Mins"),formatDate(dateAdd(prop("Day 0"), 1, "days"),"MMMM D, Y H:mm A"),formatDate(prop("Day 0"), "MMMM D,Y H:mm A")), if(prop("5 Mins")&&prop("30 Mins")&&prop("Day 1"),formatDate(dateAdd(prop("Day 0"), 4, "days"),"MMMM D, Y H:mm A"),formatDate(dateAdd(prop("Day 0"), 1, "days"),"MMMM D, Y H:mm A")), if(prop("5 Mins")&&prop("30 Mins")&&prop("Day 1")&&prop("Day 4"),formatDate(dateAdd(prop("Day 0"), 7, "days"),"MMMM D, Y H:mm A"),formatDate(dateAdd(prop("Day 0"), 4, "days"),"MMMM D, Y H:mm A")), if(prop("5 Mins")&&prop("30 Mins")&&prop("Day 1")&&prop("Day 4")&&prop("Day 7"),formatDate(dateAdd(prop("Day 0"), 15, "days"),"MMMM D, Y H:mm A"),formatDate(dateAdd(prop("Day 0"), 7, "days"),"MMMM D, Y H:mm A")), if(prop("5 Mins")&&prop("30 Mins")&&prop("Day 1")&&prop("Day 4")&&prop("Day 7")&&prop("Day 15"),formatDate(dateAdd(prop("Day 0"), 30, "days"),"MMMM D, Y H:mm A"),formatDate(dateAdd(prop("Day 0"), 15, "days"),"MMMM D, Y H:mm A")) 

I have consulted Notion AI and have tried numerous ways of inputting this code, but I always get the error "End of input expected. [410,411]"

Any help would be greatly appreciated!
