you first need to add an LCD module and then.. do step by step execution, it will show you the commands you send etc.. it help you analyze the programming is ok or not.

well.. download the all in one LCD library as example for LCD. configure the port you are going to use..
after that...
when you debug...
--
1. right click and add LCD.
2. select the make.. simple to select
3. set the ports you are using.. in the boxes.. set them as.. D:0x... some number the port you are using for LCD. e.g if you are using P0 then you can set as. D:0x80 etc.
there is a yellow '?' button is there.. to help you out.
4. start debugging.

Note: it has only 4-bit interface.. not 8-bit
----
hope this helps you

actually it will be better if you write program in your own way. i give you steps..!
send first init value - 0x30
send second init value - 0x30
send third init value - 0x30
Set the data width - 0x20
then send function set - 0x28
after that other commands.

after that it will give you the desired results just want to say.. check coding

wrt_value is not defined anywhere in the program, thats why you are getting that error.
