I have it working on the store and if you put the testimonial in to the database direct it wroks.  But if you use the admin it thows an error when you go to insert it:

It says: Fatal error: Call to undefined function: tep_array_merge() 
...admin/testimonials_manager.php on line 64


Well I changed the table names on that page but the error message is beyond me...  

This is what I have on line 64:

$sql_data_array = tep_array_merge($sql_data_array, $insert_sql_data); 


I am not sure if the problem is the database or what.  I thinkd the table is OK except I was unsure what default ' ' was so it is blank?????

Any ideas?
