Ahggg please help me

I am not a begginner and normally id post on blitzcoder but it seems to have dissapeared(anyone know whats happened)

this is driving me insain because as far as i can see there should be no problem

here is the code.change_avatar
foc=0:Gosub focus

While KeyDown(0)=False

Text 200,200, windat(0,6) ;----------------point 1



ypp=0-windat(0,6)

For v=1 To novatar
If avset>=avtype(v) Then
DrawImage avatn(v),10,ypp:
Text 10,ypp,ypp
ypp=ypp+200

End If
Next
windat(0,5)=ypp+windat(0,6)
Gosub win_draw
Color 255,0,0

Text 200,300,windat(0,6);---------------point 2


Flip


Wend
Return




now this is a simple while loop with some gunk in the middle
the problem is this
windat(0,6) at point 1 and point 2 should be the same
i can see noway that the number can be changed there it seems impossable yet at point 1 its always 0
and at point 2 its the correct number

i do not understand, can anyone work it out?
id greatly apreciate it thanks

Probably need to post more code. You've got a couple of GoSubs in there, but the subroutine code isn't shown above.

I know the thing is there are no gisubs between those 2 pieces of code, the only thing that occured to me was perhaps a while had got messed up and the wend was sending it to the wrong place but thats not the case as ive done a line by line flow test

between the 2 texts there is literally only a flip and the wend so its absolutly beyond me how it can change
the gosubs call masive sections of code running window libaries i wrote but as ive pointed out there not called between the 2 texts

apart from this gosub, you mean?
Gosub win_draw

Blitz coder's moving to a dedicated server and should be back soon.

What is

While KeyDown(0)=False 

supposed to be? As far as my docs show, the lowest scancode is 1, the Escape key. As far as the docs show, there is no scancode 0.

where do you give that variable its value??
