Help on - Handle Runtime object in QTP

[geom]

I have a .net page which have runtime generated webedit fields.Actually i don't know anything about it before running the application.I need to change the value of these runtime webedit field.
I tried to use this code,but shows error object not registered.

Code:

Set Desc = Description.Create()
Desc("micclass").Value = "WebEdit"
Set Edits = Browser("Repsmart Data Centre").Page("RDC Product").Frame("popupFrame_3").ChildObjects(Desc)
MsgBox "Number of Edits: " & Edits.Count
Max = Edits.Count -1

For x = 1 to Max

detail=Edits(x).GetROProperty("Name")
Browser("Repsmart Data Centre").Page("RDC Product").Frame("popupFrame_3").WebEdit(detail).Set "17.50"
