Error in script

[Culhwch]

I'm trying to create a feat that adds to a bard's total bardic music charges per day.

It works fine if I have bard levels, but when I don't have bard levels, anytime I pick a feat, I get this error: Attempt to access non-existent child pick "hBrdMusic' from script. What would be causing the error?

Thanks.

hBrdMusic is added by the bard class, so if the script is running, and bard isn't there - it'll look for its target.

You put a pre-requisite on the feat, requiring the bard class, right?

I think you're doing this:


hero.child[cHelpBrd].field[cTotalLev].value =
hero.child[cHelpBrd].field[cTotalLev].value + 1


The "child" transition always assumes that the specified pick
(cHelpBrd) exists. If you the pick may not exist, use "childfound" instead:


hero.childfound[cHelpBrd].field[cTotalLev].value =
hero.childfound[cHelpBrd].field[cTotalLev].value + 1


"childfound" is the same as "child", except if the specified pick
doesn't exist, it does nothing. In cases where the child pick might
not exist, you should use "childfound"; if the pick should always
exist, you should use "child", since that will give you an error if
you do something wrong and the pick doesn't exist.


You should also add a pre-requisite for the Bard class as mgehl suggested.


Hope this helps,
