Hello
In your email you can do something like that :
Red: [[+red:if=`[[+red]]`:eq=`1`:then=`Yes`:else=`No`]]
Blue: [[+blue:if=`[[+blue]]`:eq=`1`:then=`Yes`:else=`No`]]
OR
[[+red:if=`[[+red]]`:eq=`1`:then=`Red`:else=``]]
[[+blue:if=`[[+blue]]`:eq=`1`:then=`Blue`:else=``]]
If you want to have a list of the checked boxes you’ll have to write a snippet that loops through the checkboxes, and output the list you want.
Hope this helps
Cheers
EDIT : As you use an array of values (’colors[]’), I saw recently that you can also do something like
[[+colors.0]]
[[+colors.1]]
I hope one of these solutions work for you
