**AJ**I can't get the form calculation feature to work for a drop down box.

It says in the instruction that calculations will work for drop down boxes, check boxes etc.

But its just calculating zero.

Can you tell me what Im doing wrong?

My drop down box looks like this -

Product One £199

Product Two £399

Product Three £599

Do i need to be entering the prices in a certain way to allow the function to recognise the pricing to add it?

**david**Hi,

You are almost there, all you need to add is the value for each field. So for your most recent form:

The 0.00 value represent the empty default selection. These will be the values associated with your calculation.

Let us know if you have any further questions and we will be happy to help.
