Hello,

In RSFromsPro I have made a form with fields for calculation purposes. I want to calculate with the selected dropdown value in a formula. I have this:

Field = ({Total:value}*{BTW:value})

The dropdown value (= BTW:value) does not work in the calculations. Every other value in a text field of my calulation does work but not the dropdown value. What am I doing wrong here, how can I select the dropdown value in my calculation other then {BTW:value}?

Please make sure the "BTW" field has a value and you are using the proper syntax. Please refer to this article for further information: . If your still having problems, please reply with more information so we can see what it's going wrong.

Yes I have tried to find the right syntax and have used several.

My example is located at: service.andrerioleringen.nl/

The second value BTW laag is not working for it has the dropdown value {BTW1:value} in the calculations.

I have created a backup file of the form to be downloaded here: service.andrerioleringen.nl/images/rsfor...014-06-10_082623.zip

My calculations list for reference is here:
Totaal1 = {Uur1:value}*{Prijs per stuk1:value}
Totaal2 = {Uur2:value}*{Prijs per stuk2:value}
Totaal3 = {Uur3:value}*{Prijs per stuk3:value}
Totaal4 = {Uur4:value}*{Prijs per stuk4:value}
Totaal5 = {Uur5:value}*{Prijs per stuk5:value}
Totaal6 = {Uur6:value}*{Prijs per stuk6:value}
Totaal7 = {Uur7:value}*{Prijs per stuk7:value}
Totaal8 = {Uur8:value}*{Prijs per stuk8:value}
Totaal9 = {Uur9:value}*{Prijs per stuk9:value}
Totaal10 = {Uur10:value}*{Prijs per stuk10:value}
Subtotaal = {Totaal1:value}+{Totaal2:value}+{Totaal3:value}+{Totaal4:value}+{Totaal5:value}+{Totaal6:value}+{Totaal7:value}+{Totaal8:value}+{Totaal9:value}+{Totaal10:value}
BTW Totaal = {BTW 6:value}+{BTW 21:value}
Totaal = {Subtotaal:value}+{BTW Totaal:value}
BTW 21 = {Totaal1:value}*0.21+{Totaal2:value}*0.21+{Totaal3:value}*0.21+{Totaal4:value}*0.21+{Totaal5:value}*0.21+{Totaal6:value}*0.21+{Totaal7:value}*0.21+{Totaal8:value}*0.21+{Totaal9:value}*0.21+{Totaal10:value}*0.21
BTW 6 = ({Totaal1:value}*{BTW1:value})*0.01

In this last calculation (BTW 6) I am trying to use the dropdown value.

You will have to change the items from the dropdown fields from
6
21

to

6[p6]
21[p21]

Thanks that's it it works, I may have overlooked this in the manual/example page or prehaps it's not clear that you have to adapt the fields in the items box.

Guys, I have a client that is running a registration and I need help. Using rsform pro and joomla 3. The form is working fine for most users but from 15 who registered 3 registrations form resulted in 0. Although the default value of drop down list price is more than 0 to begin with and I used Multiple Product for dropdown.

Any ideas??
