Product Type - Fatal error: Call to undefined function

[DeeR]

Dear people,

apologies for not knowing what I'm doing. Hopefully I'mposting in the correct area, I'm sure I'll be told to move if I've messed up.

A friend who runs his own small business has asked me for some help with his website issues and this ZC error is a long time problem for him.

When logged in as admin and selecting pull down menues:
Admin / Catalog / Product Type

This error line is displayed along the top (just below the meu buttons)

Fatal error: Call to undefined function:SHOPNAME_zen_cfg_select_drop_down() in /home/httpd/vhosts/SHOPNAME.com/httpdocs/store13/admin/product_types.php(248) : eval()'d code on line 1

and the line (248) in that file (product_types.php) that it seems to be referring to is:

eval('$value_field = ' . $cInfo->set_function . '"' . htmlspecialchars($cInfo->configuration_value) . '");');

Hopefully someone has an idea, and of course feel free to ask me for some info I've neglected to include.

I've no idea about ZenCart's inner workings, nor am I sure what number of plugins the owner has already installed on this setup is.

Regards

D

The pulldown boxes in the right-hand sidebar of the admin area are built from a function named zen_cfg_select_drop_down().
NOWHERE does Zen Cart call the function by SHOPNAME_zen_cfg_select_drop_down()

So, that suggests that whoever set up the site or wrote addons or customizations for it has made an error in one or more of the set_function fields of the product_types_layout table, which is where the calls to such a function are stored as it relates to product types.
