Darrel,

thx alot for helping, it worked really well.

i always wished to thank you in person. cuz from 3 years i enter this forum as a visitor and i always see ur post. you always find the solution. thx much Darrel.

still i have a problem i didnt mention. the first row always doesnt give full brightness when it is on. i suppose this relates to the previous problem. i will try to work it out.

thx again Darrel.
