If condition not working in member formula

I am trying refer a intersection in member formula and apply condition based on the referenced cell.

Dim nvASP As DataCell = api.Data.GetDataCell("A#[ASP (£)]:F#No_Curr:I#None:U1#[Adjustment (Override)]:U2#None:U4#None:U5#None:U6#None:U8#None")

If nvASP.CellStatus.CellAmount = 0.0 Then

api.Data.Calculate("F#No_Curr:O#Forms:U1#Total:U2#None:U4#None:U5#None:U6#None:U8#None:I#None:A#[ASP (£)] = F#No_Curr:O#Forms:U1#Calculated:U2#None:U4#None:U5#None:U6#None:U8#None:I#None:A#[ASP (£)]")

Else

api.Data.Calculate("F#No_Curr:O#Forms:U1#Total:U2#None:U4#None:U5#None:U6#None:U8#None:I#None:A#[ASP (£)] = F#No_Curr:O#Forms:U1#[Adjustment (Override)]:U2#None:U4#None:U5#None::U6#None:U8#None:I#None:A#[ASP (£)]",,,True)

It does not consider the if-else condition and just process the first condition .
Something which i am doing wrong in here ?
