Object Property Value = Code but not static value

Hello Friends,



I dont have any unique properties populated for a text box. But there is a label (different object) which has the an index always greater than 1 and I want to use it

example

- Panel1

--- Label("Acc.No",2)  -- this is the label

--- Textbox("edit",1)  -- this is a text back which has index one less than the label index



Now what i want to achieve is



Map Textbox("edit",1)   which will have class as "edit" but I want to use a code in index property something like this



index = (go find an object which has label = Acc.No & get its index and subtract it by 1 and use that value)



how can i? is it actually possible?



Thanks

Pravin
