I have tried

as well Velocity 1.7 fails when it reaches the range variable in the

Is there a way to accomplish what I am trying to do, (a variable count
loop) in velocity?
The error is that you're not actually iterating over a range, but trying
to iterate over a string.
#set($range = "[1..$n]") => $range is a String
#foreach($i in $range) => $range is still a String, it won't be replaced
with [1..$n]
This should work:
#set($n = 2)
#foreach($i in [1..$n])
If you must define the range somewhere else as a string, you can use
#evaluate to dynamically interpret the range, but that adds unneeded
complexity.
