I'm struggling to make sense of your help file re the Payments Multipliers configuration. The help file suggests that I can do what i wish to do, which is set a fixed fee of £10 then give options of add ons option [1] £33 [2]£66 and [3] £99 so that if the user selects, say option [2] they would be charged £76 in total or option [1] they would be charged £43 in total etc, but for the life of me I can't work out how to configure the form to do this

On your form, say you're selling 'widgets'. Each widget cost $5.00. You would have a field (number). The title of that field could be something like 'Widgets $5.00/each How many would you like? (1-5)' The user would then input a number from 1 to 5. Nothing would show on your form other than that number. But when the form is submitted then the paypal screen would show the total multiplied by 5.00

On your form you would select the number box, then click the properties tab. Come down to payments and select 'price multiplier'. Then in the box that appears below that input the basic price of $5.00 (or whatever).

Again, you won't see the actual total on this page unless you modify the code yourself. Eric may be able to help with that if he pops in. But it should show up when submitted to paypal.

Hope that helps.

I was wanting to use 3 Radio buttons, 1, 2, or 3 months, so I'll set each one as Months 1: Months 2: Months 3:What then do I put after each colon? Lastly just to make sure I understood you correctly, if I use the Price Multiplier using the Radio Buttons as a multiple of £33 and in the Payment tab under settings select Fixed Amount £10, then that will add the multiplier of £33 to the £10 base, correct?

That's excellent, thanks, and in the Payment tab under Settings tab I also need to make the Fixed Amount £10,correct? so then the £33 multipliers are added on top of the £10 base charge

That is correct. Check it out here ... http://gunsmoke.me/h/test3

The base price you set in the settings will be added to whatever you pick off the radio buttons.
