Add 2 variables together to make another variable
What am I doing wrong here to get undefined variable notice.
if (isset(${$error_description_.$i}[$lang])) {
Previously I had this:
if (isset($error_description_1[$lang])) {
I now have this inside a for loop where 1 is replaced.

This should work:
if (isset(${'error_description_' . $i}[$lang])) {
}

It should be:
if (isset(${"error_description_".$i}[$lang])) {
