Connect two forms

hi friends, I have problems against ODK Form, I've worked at a company that uses ODK Collect in a data collection. so when we collect data from households that took on the "Fill Blank Form" and in the household there are women of childbearing age, it will automatically connect to form women of childbearing age, so that when filling out the form of women of childbearing age not through "Fill Blank Form"but through" change saved form ". and in "change saved form", we click on the name of the household then will appear the names of women of childbearing age, then we can change normally. how to create those links in XML dat XLSForm????

Please Help Masters, Because I Have made it for this year and nexts
