what is the problem vith pic or LCD...

Hi every one.
I finished below project for counting. Define as folows.But not work.
I use Pic 18F4520 4 MGZ osc.

please look at attachment for LCD wiring

This is just an example for a 18F452 ... with a 2x16 LCD

Thanks for your information. My programer does everting .(config...)

I find the problem mysel.
I put a capasitor (47mF) between MCLR and nengative port and problem was dissdlwed.
Thanks.
