I'm getting the following error: 

"Can't call method "date" on an undefined value at ..."

[download]

on the following line: 

"$$xp1[$x]->date($$xp[$x]->date);"

[download]

As you can see, I'm filling the date of one object(contained in an array of such objects (ie - @$xp1 were $x is an incremented value based on the size of the array), with the date from another such array (@$xp).

Just to be clear, the array on the right is full of data that I can print, and the array on the right is full of objects that I'm able to assign to outside of the loop. I thought it could be a problem with the increment value, but I haven't been able to test it, and here's why --

If I put a print statement ahead of this line, any print statement, the problem goes away. So if I print "hello world" before executing this line in the code, the code works. I just don't get that. Please help.

Update: Scratch the question - the act of posting the question clarified the issue and I solved it. thanks anyway.
