Can you give us a hint as to your problems? Context of this line?
Errors you're getting?
Can't say much about one line out of context.

Assuming this is a MySQL query...
Don't quote the column names, they are being treated as literals.
Multi-table updates only work with version 4.0.4 onwards so make sure
you're using that or a later version.

Thanks, its an mysql quesy yes,
and i also tried it without the quotes:
mysql_select_db ("idm") or die("Unable to select database");
$query = "update reactie,form set reactie.persema il = form.email where
reactie.persid = form.id ";
$query_result= mysql_query($qu ery) or die ("can not change the data");
echo "<b>The data is succesfully changed</b><br>";
but it said to the cant change the data, whats wrong here?

I just created a couple test tables and ran your query and it works
fine for me, so...
Do you have a unique index (or primary key) on the persemail column in
the reactie table? Maybe your update is trying to set a duplicate
value?
You should display the text returned by the mysql_error() function
following your call to mysql_query(). That will tell you what is going
wrong.

For this particular query it only really matters if reactie.persema il
is a unique index - i.e. if it was, then you might be trying to set it
to a duplicate value.
Try my other suggestion by changing your query line to be..
$query_result = mysql_query($qu ery) or die ("can not change the
data: " . mysql_error());
That will tell you exactly what is going wrong.

Thanks, i tried your suggestion. But it doesnt give me really the
information i need. i get this:
can not change the
data: You have an error in your SQL syntax near 'form set reactie.persema il
= form.email where reactie.persid = form.id AND reac' at line 1
But i think i know the problem now. form.id is a primary key so has unique
values and cant make duplicates. Is there a way to change this ?

No, MySQL is telling you exactly what's wrong - there is a syntax error
in your statement. It never gets far enough to update the database, so
you can't have a problem with duplicates (plus, you aren't changing
form.id or inserting a second row with the same id, so that's not the
problem anyway).
So - back to basics. What version of MySQL are you actually using? And
what's your table layout for form and reactie?
