Fatal Error: Call to undefined function

[Guest]

Help! Everything downloaded fine and uploaded without a flaw as well. I access the index.php file without a probelm, but when I click on the new install button, I get the following:

 

New Installation

 

Please customize the new installation with the following options:

Import Catalog Database:

Fatal error: Call to undefined function: osc_draw_checkbox_field() in /home/eppie/www/store/install.php on line 24

 

 

What can be done to fix this?

 

Your help is greatly appreciated - somebody be a hero.

thinking you need to reupload the app to your server.
