entering line number from all-data sheet that will autopopulate info into a form

hello!
i am in need of help with some kind of formula, i hope there is a way to even do this.
here's the situation:
say on the 1st excel sheet cells A2-A5 list one customer's name, address, etc. along with their specific customer needs. this is a generic form that can be updated with different customer's info.
on the 2nd sheet is a spreadsheet with every customer's name, address, etc.
here's what i want to do:
use a cell outside of the specific customer form, say K1, and enter the line from the all-data sheet for the customer's info I want to input into the main form. so say on the all-data sheet customer number 11 is Joe's Business.
In cell K1 on the form, I can put 11 and Joe's Business information will auto-input into the form..
Does anyone know if this is possible?
Thanks in advance for you assistance!
