Default max record

Hi all,

Description of my tables:

table1
idfield1
namefield1

table2
idlink
idfield1
idfield3

table3
idfield3
namefield3

table1.idfield1 = table2.idfield1

On every record of table1 they may be one or more record on table 2.

Now I've tho find all record from table1 in wich the last value (ordered by
idlink) looking for a value in namefield3.

I've tried this:
select table2.idfield1, max(idlink)
from table2
inner join table3 on table2.idfield3 = table3.idfield3
where table3.namefield3 like '%searchtext%'
group by table2.idfield1

max(idlink) return the idlink where searchtext is found. Instead I want only
the record where max(idlink) has the idfield2 to the searched value.
example values:
I'm looking for idfield3 = 5
For those records in table2 (idlink,idfield1,idfield3)
1, 10, 3
2, 10, 5
3, 10, 2 //(last value for idfield1 10 is 2 so not in result)
4, 15, 5
5, 15, 8 //(last value for idfield1 15 is 8, so not in result)
6, 8, 3
7,8,5 //last value of idfield1 8 is 5, so I want it)

How to do so ?

This is part of a subquery, I can only have 1 result.
