Stupid questions on variables gained from a MySQL DB

I have a table with a column for first name and a column for last name. On another table I have one column for name. I am tyring to get the first table to insert the name into the second table. But I can't seem to combine the variables. here is what I got



It doesn't work. I looked at the manual and it doesn't show how to combine 2 string variables into one.

simple answer,

$name1 =$result[firstname];
$name2=$result[secname];

$name=$name1."".$name2;
