bit of a maths help if anyone can?

[Gibbon]

Hi, im after a bit of help.

Basically, imagine a line thats 250px long

and i have a slider bar that the range is set to 0 - 100, i want to be able to move the slide and it changes the size of the line, slider at 0 makes the line 0px and slider at 100 makes the line 250px.

how do i go about this?

Thanks
Andy

Hi. First of all, change the slider bar's range to 0-250?
If you don't want to, just use value("slider")*250.0/max("slider")
I'm not sure what you mean by line. An active, a picture, an overlay? Please be more specific.

[Gibbon]

Well.. neither, i just used it as a easy example to explain the values i needed.

And unfortunatly i changing the slider range isnt an option as its a percentage

Thanks, ill try what you have suggested.

Hmm that works, but only for making the line (or 250 value) go down, if i move the slider back up, the line value keeps on decreasing.

Any more ideas?

Thanks

Ouch. I kind of skipped the 'imagine' part. :blush:
It can't be the formula's fault! Maybe the line updating code is faulty.

[Gibbon]

No probs.. Hmm cant see that...


+ set line height to
- value("slider")*250.0/max("slider")

When you move the slider down the line value will go down, move it back up and the line value keeps going down...

Thanks

Seems like you are modifying one of these slider values while updating. There's no way it's the formula!

You right, i aplogise, sorted it. Thanks for the help pal.
