kglad,
I am still a little confused. What is a and b representative
of.
I understand I need to solve for them but I dont know what
those numbers relate to. Height or position of what?
>>Stage.height-Thumb_Slide._height=a*(-150)+b;
I can find the stage height, so this doesnt make much sense
>>0=a*(-255)+b;
This is totally confusing. But strangly - I didnt know how to
multiply with a negative number. thanks
