# Find MAX value from array of variables?

Is there any way in EPDM to find the max value from an array of variables?

I want to use a weighted rating system for checkboxes.

I need to be able to determine the highest point value of the checked boxes, as well as the total of all the checkboxes on the card.

e.g. say I have 5 checkboxes with the following point values:

chk1=1 point

chk2=1 point

chk3=2 point

chk4=2 point

chk5=3 point

So if the user were to check:

chk1 and chk5

Then the max value=3 and total=6

Or, if the user were to check:

chk1, chk2, and chk3

Then the max value =2 and the total = 4

Hope that makes sense.

My first thought is that I can tie the checkbox to a non-visible editbox and use control logic to set the point values.

e.g. if chk1 = 0 then edit1=0

if chk1 = 1 then edit1=1

if chk2 = 0 then edit2=0

if chk2 = 1 then edit2=1

if chk3 = 0 then edit3=0

if chk3 = 1 then edit3=2

etc.

I could then get the total using an input formula on another editbox and adding all the variables...but what I can't figure out is how to determine the max value??

There doesn't seem to be any support for this in the mathematical operators available.
