Intersting problem in QTP

[anshu.khandelwal]

I'm stucked in my new and very first QTP assignment:
1)How to capture data from and output parameter I written code

Code:

Dim return
return =   Window("Display").Dialog("Itinerary. 30.15 km. 24").Output CheckPoint("Itinerary. 30.15 km. 24 min, 25 sec_Source")

it's giving syntax error:expected end of statement?
Can any QTP expert help
