get an existing variable to show in text when using newitem

[Kevin]

is there a way 2 use an existing variable and get it 2 show that var value in the text part of newitem.I am creating function on the fly using newitem and i need 2 be able 2 pass a variable to the text part and have the variables value show up in the new function.
ex..
str a.getwintext(win("windowname" "windowclass"))
newitem a "<need str a's text here>" "Function" "" "test"
but i also have alot more text to input but i can't seem to get str.a text to be displayed
