On you purchase order template place a <cfajaximport tags="cfform"> tag so that
it will import the libraries neccessary to run a cfform in a cfwindow. since
you have a cfgrid in your cfwindow you will need to do <cfajaximport
for mor on cfajaximport read
Also I wouldn't name both the text input and the button and the cfwindow all
"employee", name the text input employee, the button employeeBtn, and the
cfwindow employeewin or something, but not all the same name as that can
potentially cause confusion and problems.
