Fixing Monthly Cash Flow Report (was Re: How to add reports into Gnucash)

[David T.]

David--

I have poked around the Gnucash svn site looking for what to do, and I turned up a number of changesets revolving around renaming gnc: functions. These include: 14959, 14961, 14962, 14964, 14965, 14968, 14976, 14979, 14980, & 14981. Each of these included a set of string replacements, which I put into one big file and applied to toodles.scm using sed. The output file I named (for some reason) buggy.scm.

Unfortunately, even with these changes applied, I get errors. I see that I still have a lot of references to "gnc:" calls, which I gather from what I found on svn is being phased out for something better. Many of these calls didn't turn up in a search of the svn site, so I don't know what they ought to be.

I have attached both buggy.scm and the console output from the Gnucash session that would not load the report. If I am even remotely on the right path, please let me know, and if anyone has a suggestion on how to proceed from here, I would welcome that.

David

P.S.- I note that even though one of the lines included in the svn changesets changed gnc:get-current-group to gnc-get-current-group, that unbound error remains...
