@
Maceart and (especially)
test:
A real pity that
(a) you "automatically"assumed we didn't take your remarks seriously;
(b) you apparently didn't take our remarks seriously enough to check;
. . . (Tizio in fact already gave you the solution in the 3rd post of this thread!)
(c) you didn't simply ask if you didn't know where/how to find equalizer.
You really kept us busy and puzzled!
Anyhow, glad your problems are solved now.
