imported customers info screen not working

I imported the customers and customers_info tables (from an OSC customers list by copy and pasting the content of the appropriate columns into the same columns in the ZC table) and the customers show up in the admin area, but clicking on the i for info doesn't make a blue arrow and of course clicking the edit button doesn't show the customer's info. I've compared the tables from a functional ZC installation on another domain, but can't spot any difference. Is there another table required for the info/edit screen to work, or something else I'm missing?
Thank you,
Michael

I don't think you can just cut and paste, there are some tools for transferring data between zen-cart and osc in the free software add ons sections, and there more on this subject if you search the forum.
