I'm coming to you because I don't understand where I made a mistake
So my problem is with the display in my drawing of my "MT" property
To have "MT"
the choice is between "Several machines" and "One machine".
If you choose "several machines" in my drawing, it is displayed, on the other hand, if you take "one machine" and choose as you go in the drop-down lists, nothing is displayed.
Is the expression <>" good? It's mostly about the double quotation marks, is it good like in Excel to check an empty box? (empty box I'm talking about the form...)
We agree, I don't know any more than you do at the moment, I'm trying to point you in!
No none of them work, it must come from the test, I have to figure out how to do the test to know if the property from a drop-down list is empty or not
In fact, the "IFF" function works in a certain way, plus the aid is wrong but it will be done again soon that's what I was told.
So the IFF function, works in the following way, after doing the test, you absolutely need a variable, you can't put another condition "IFF" after the test, to be more precise if this is not the case and for those who know excel:
Si=(logical test;[ value so true]; [value if false])
Sorry but I don't understand what changes between your initial question and your answer apart from what I told you, namely to remove the quotation marks to make the "zero value" understood?
I must be missing something but I really don't see what it is?
Well I'll tell you what you missed, in fact nothing at all, I was the one who got my brushes confused, you're quite right, I'm sorry because you were the one who gave me the right answer, but as I stayed more than an hour with the Axemble technician and we did and redid the formula, I got lost.
