I purchased book but examples of JavaScript give me errors. I wonder if it is because of differences between Netscape and IE. Is there any good references one look at to get hints as to the differences?

I have Microsoft IE6. Does the MSE recognize JavaScript or is it looking for JScript? And could this be my problem?

Thanks for any information!

Uless you post the specific code fragment and the error that is being caused it really not easy to guess.

Cheers

Okay here is the code. I am having problems with the functions. I get an "object expected" error. I copied this from a book and I haven't been able to figure out what is wrong!
I have Windows ME, IE6. Thanks for any help!

Thank you very much. I was trying to figure out my mistakes and I made plenty but I was looking in the wrong places. I am new at this and was surprised to find out that mistakes on down in the code can cause things that are correct in the beginning to show as errors. I thank you for your time.
