Hi jimns

PS I Assumed that you have in database the price from article correct assigned

in this case you must modified the form to use "length" in case that you have for example cable instead quantity (in one form this is difficult to perform but not impossible)

if you do this then you can use some calculation to count the total price

I suggest to use 2 forms to do this, it will be simpler

---

If I understand you correctly I see the problem but I do not know how to solve it.
If you see FOTO#1 In standard F02_005 I have 3 cables 10 meters each one (3x10=30m), price 8 PLN/m and 3 switches 15 PLN/piece.
"Suma całkowita" (bottom of the page - I am sorry I do not have English version of Eplan) I have 69 PLN.
Why?
Because Eplan calculate it as follow:
(3cabels x 8PLN)+(3switches x 15PLN)= 69PLN
Eplan calculate 3cables, not 30meters!

eplan calculate this correct but you think/use it wrong

its so simple but also very complicated

first this form its for "quantitative" articles - not for "in length"
if you wont to use this in "length" articles you must modified the form to include the "length" in quantity
