Error in calculation in Adobe 8 Pro

Be more specific about what is going wrong, please. And also share the file in question with us, if you can.

Also, which version of Reader is your user using?

I will attach the file so you can see. But question: How do I attach a file to this post?

I don't think you can. But you can upload it to adobe.com or a site like rapidshare.com and then post the link here.

The file in question is posted here:

The errors are intermittent and usually occur in the "Tip" row. The errors occur when I use the form in Acrobat 8 Pro, and my user is using Acrobat 9 Pro. But it also happens in Reader 9. Totally not selective! Thank you in advance for your help.

In the Custom calculation script of the Tip field you have an error in the following line:
var b=this.getField("Tip Percent");

There's no field called "Tip Percent". Only "TipPercent" (no space).
Fix that and the rest seem to work fine.

P.S. - in the future, use more descriptive variable names. It will make it easier to debug.

I fixed those errors and it will calculate properly -- but only one time. After the proper calculations, if I change the input data (number of guests, amount for fees, etc.), the numbers may -- or may not -- recalculate.

I've uploaded two examples (not in editable form). In the first example, the tip row is not calculated at all, all the way across. In the second row, the tip row is calculated. The only thing I did to the actual form was open up the calculations edit box and close it again -- I made no changes to the formula -- and it calculated.

Also, what did you mean "use more descriptive names for variables?" Do you mean instead of "a" or "b", I can use "var.tip" or "var.guests"? That would definitely make it easier.

You need to set your field calculation order in the correct sequence. For example you 'Tip" field is the 3rd from the last calculation performed. So the tip value is not being included in the 'TipTotal' field that has already been calculated. If you put '0' in the Guest field, the form information will not change, but the form will recalculate correctly since none of the base calculation values will have changed, but the correct values will have been used.

I took all your suggestions and completely re-entered the form. It works! Thank you so much for your help. I'm now a believer!
