Hello, before I continue I would like to let you guys know that I'm a novice using Circuit wizard.

I'm using the Genie E18 board (it's a must) and I'm trying to do so that I can press a certain number. For clarification, Pin 1 (row 1) and pin 2 (column 1) should result in the number 1 as it is the intersection of the two pin. However It seems that I cannot figure out how to make it so that it would ONLY be number 1 and not the rest of the numbers on row 1 and column 1 (2,3,4,7,*). So my question is how do I programme so that it would only be a CERTAIN number and not the whole 7 numbers (3 in a row, 4 in a column)?

You cant make lines high and low. You have to have inputs and you need pull up resistors.
You need 5 years of electronics study before starting to develop a program for a keyboard.
