Show dynamic values at listbox depending value selected another listbox

Hi everyone

I'm starting with vba early and I don't know mucho more for now. I'm trying to put some value of a range at column A that have variable size and show into ListBox2 the values are at his row (also variable size).

for exaxmple If I selected value from a2 at ListBox1 show at Listbox2 values from B2 until column2 that have values (in this case C2). If select A3 show B3 until C3 ....

Also I want to do this with arrays and give the posibiliti to update this values (remove, adding or modify). I think this must be make it with cycles for or something and property ListBox Selected but I don't achieve the solution. Any help will or sugest how can read will be fantastic

I upload a test file I beguinin with, it is por and badly and I know it have lot of mistakes (names given to the arrays) etc. I'm working in it.

For mistake I upload the file and message at General forum and I don't know how to move to this forum. I linked it in order to give access to the file I've upload http://www.excelforum.com/showthread.php?t=1171200&p=4567748#post4567748
