how to calculate the true values of dropdown/checkbox items

Hello @krstnz

Thank you very much for using our plugin.

Assuming you have two fields, the dropdown field fieldname1 with the prices, and fieldname2 a number field for quantity, you must insert a calculated field in the form and enter the equation:

fieldname1*fieldname2

Note the choices’ values in the dropdown field (fieldname1) must be valid Javascript numbers without currency symbols. In javascript, the decimal symbol is the point and not the comma (Ex. 11.32)

If the equation results are currency values, and you want them with two decimal places, you can use the PREC operation as the outermost operation.

PREC(X, Y) rounds the number X with Y decimals.

Continuing with the hypothetical equation above, you can edit it as follows:

PREC(fieldname1*fieldname2, 2)

Best regards.
