Object Expected, need help

23
Line 22 Char 1 says object expected in the following code. For the life of me I can't figure out what it is. I'm sure I'm just overlooking some stupid bit of formatting or something.

Did you forget to close the "()" in both "if" controls, or it is your code?

This is a syntactical problem.
The error message never comes with Syntactical problem.
Having runtime error it happens .............
I think he mistyped.

But Now I get Lines 7, 8, 17, & 18 chars 5 'MyIFrame.style.zoom' is null or not an object which I can get rid of that by removing the .style from there, but it still won't do what I want it to, which is to change the zoom on the iframe. I must be missing something.

Is this "MyIFrame.style.zoom" a standard attribute.
I don't know.
Actually I am not very much familiar with CSS :-)
Can't you do it using change the size of "IFrame"?
Means ..... "style.height" and "style.width".

Well, if I change just the height and width, then the contents of the frame won't shrink or grow with the frame, it will only change the viewable area. That's why I've got to change the zoom style somehow.

The effect I'm going for here is to have a background image of (for example) a face, and the iframe will start out super-small, like around 2% of it's original size, and it will be placed over the pupil of the eye without borders, so that it almost looks like it's part of the picture, but when you mouse over the eye, it zooms the iframe in, which would contain a rotating ad such as a google adsense ad. I have done that already with just putting the final zoom size in the onmouseover event handler, but that doesn't provide the smooth zooming effect that I'm going for here.

As far as I know, .style.zoom is ok... there's a script here: http://msdn2.microsoft.com/en-us/library/ms535169.aspx

That uses it, and that script works (although they named their ID ozoom instead of MyIFrame, so in theirs it's ozoom.style.zoom, but it should work the same).

Then you have to wait for a CSS experts.

Ok, so I changed and simplified the code, everything works now with no errors, with only one problem. If I mouse out before the iframe has finished zooming in, it stays at it's zoomed in size until I re-mouseover and mouseout again. If it absolutely has to work like that, ok, but I'd prefer it not to. I need one command to get this part to work as well, I need an IF statement that checks to see if the mouse is still over the object. Does such a thing exist? I know it's a long shot due to the redundancy between that and an onmouseout event, but I can hope, right?
