Hi,
I’m building a form in cff. In a specific part, the users have to enter the sides and area of a space. FYI, this area is the accurate one gonna be used in future calculations. but I need an error for the case they make mistake. for example they enter 6 & 10 as sides but 600 as area. So i have to calculate the area with a tolerance of 3% myself to double check.
The problem is I don’t know how to define the error. if the entered area is close to my calculation, the process should go on, but if it’s not, I need to stop the process and ask the user to check his numbers. I know the condition, but don’t know the TRUE or FALSE definition in this case.
Would you please help me?
