I am new to PERL and am trying to pull values out of an iteration in my presentation template, and then sum them together. I have attached my DCR & IPL. Any advice would be much appreciated.

Could you please explain as what error you are getting after running your program?

Where you have instantiated the variables being in use.. for calculation.? $amount and $forecast??

I was told I did not need to instantiate $amount or $forecast because it was enclosed in CDATA. I am still trying different things because of my inexperience with PERL. I thought that if I pulled out w.col_2_data of each iteration and assigned it to $forecast as a += it would sum, then output the sum in the following line. But it is only outputing '0', which leads me to believe my w.col_2_data variable has no value assigned to it.

You need to use iw_value tag to pull the data inside the CDATA section you can't just use the XPATH to reference the value. You can get more information about iw_value tag http://support.interwoven.com/library/devel/tst/pt/TeamSite__PT__iw_value.html
