Check boxes

Hi I have a form which has multiple check boxes. I have a list of labels that are named chkjob1, chkjob2...chkjob6,

I would like to create a function that checks all the check boxes for a job when the label is selected/clicked. so once you click on a the label for the job e.g jobA and hit run the details of the job (jobA) will be passed into the fuction which would have an array that would build the names of check boxes and select the row.

eg

form
if label JobA is selected then
pass jobA into the function ()

Function()

chk & jobA & (i)
= chkJobA1. value = true <name of check box>
repeat for all six check boxes.

Please email me if you do not understand what I mean.
I want a seperate fuction so that it can be used for multiple jobs, without endless code.

Many Thanks

Chloe
