TOPIC: Custom Field Fee- Precentage not calculating

Hello, Does anyone have a solution for this one... i must be missing something!?!

I setup a custom filed called TAX and set it as a fee field of 7, as a Total Percentage. However, no matter how i enter it, it simply adds 7 dollars to the fee, not 7 percent. (7, 7|, 7 |, 7%, etc.) I tried 100, and it added 100 dollars didn't double the fee. I want to make this a tax field a use it across all the events, so don't want to have a set dollar amount as each event fee is different. Also, other custom fields have fees attached, so need to calculate tax based on what they select as extras...

Any tips for me? Thanks,

Maybe:

0|7

I use a dropdown for tax
Include tax no / yes and i have filled there in by fees:
0|19

There will be added 19% to total prices

Drop down wont work i dont think, as TAX is not optional. They must agree to it, so i wanted a required check box... I will play with 0|7, however i only have one check box, so should only need one fee. good food for thought. Ill do more trial and error now. Thanks.

I will try with a checkbox and let you know

Hmm, checkbox is difficult. I don't got it working yet
Radiobutton Is working, but if i change field to checkbox its not working

I could perhaps use a radio button, and just have one button... altho a check box would look a whole lot better. It would be nice to have it work....ummm
