Why will the shipping field not go to zero once $100 total has been reached

I have conditions setup to add $9 if the subtotal is below $100

Or add $0 if the subtotal is over $99

It adds $9 regardless.

Also, why can the subtotal not be manually changed by the user, but the shipping and GST can be?

Thx

I test your form, and I can immediately see what is not working.

The "Cost for each Print" is always at zero(0) only... so nothing is being calculated across all the numbers.

I suggest that on testing your form, you show first the hidden fields that have calculations so that you can see if calculations are really working

when I did this on a test form, the Cacl field is not doing any calculation

Please review this user guide on how to properly Assign Calculation Values to dropdown field selection.

Hope this help. Do let us know if you are not able to do it, and we can assist you further to accomplish the requirement.

Thanks.
