Repeat for each element failing

[Bob Sneidar]

Hi all. 

I have an array of arrays (think dgData) and I am starting a repeat loop like this:

repeat for each element aSiteRecord in aSiteData
   ...

I verified aSiteData is an array of arrays (it's the dgData of my sites datagrid) but when stepping in the debugger it goes right to the next statement after the end of the repeat loop without executing anything inside it. 

Is it legal to have arrays for the elements, or is it restricted to values?
