Hello @franckw
Thank you very much for using our plugin. The process to build a volume calculator form similar to the page you sent me as a reference is very simple. I’ll try to describe it with an example.
Assuming you have three furniture pieces:
“Bureau large” whose volume is 0.8 m3
“Grande commode” with 0.25 m3
And “Lit king size” with 3.6 m3
Each piece of furniture has a number field associated, configured to accept digits only, fieldname1, fieldname2, and fieldname3, respectively.
To calculate the total volume, you should insert a calculated field in the form and enter the equation below into the “Set equation” attribute in its settings:
SUM(0.8*fieldname1, 0.25*fieldname2, 3.6*fieldname3)Best regards.
