Hi again,
No response to my first distress call, so I thought maybe some more details would help.
When I insert some print commands, the assigned "counter" (u_*) variables exist, but are reported as being equal to zero (0). So, it appears that the original assignment is "taking".
Except that when I look at all of the variables by printing <dtml-var REQUEST>, the same variables appear as being equal to one (1), so it seeems like the incrementing is happening.
Except that, the number never increases beyond one, so that it seems that what appeared to be incrementing was really just re-setting the variable to zero plus 1 (0 + 1), as if each pass through the loop is refreshing the values to the original assignment.
I tried this: <dtml-let i="0"> <dtml-in "_.range(100"> <dtml-call "REQUEST.set('i', i + 1)"> <dtml-var i> </dtml-in> </dtml-let> and got: 0 0 0 ... 0 Then, I changed it to: <dtml-call "REQUEST.set('i', 0)"> <dtml-in "_.range(100)"> <dtml-call "REQUEST.set('i', i + 1)"> <dtml-var i> </dtml-in> and got: 1 2 3 ... 100 I haven't had a chance to peer into the code and see how let is implemented, yet, but it is my guess that dtml-let is defining the variable in the *local DTML namespace*, and REQUEST.set('i', i + 1) is setting the value of 'i' in *the request* to the local value of i plus 1 each time through the loop, thus always outputting 1. Initializing i with a simple <dtml-call "REQUEST.set('i', 0)"> makes the inside of the loop uniformly access 'i' in the REQUEST. Of course, I could be wrong. :)
Thanks for looking at this silly thing,
Hope this helps!
