Input box entry updates whole construction

Needs Answer

Hi,

when I enter solution in textbox for the first time, whole construcion gets updated making possibly correct answer wrong (since it changed).Also, I cannot make my variable "unos" defined as imlicit function on the start (which would solve the problem) because then I will not have empty textbox, but "?=?" and I need it to be empty.

Also tried to enter equation solution as text (not as implicit function) but then it says it's incorrect when I compare it to solution converted to tekst.

Does anyone have suggestion how to fix this?

Thanks!

Maybe with this possibility:

A text field is assigned to the InputField.
When updating the text field, a script is started that converts the text into an equation using Execute.

Attached a sample.

Thank you so much! That's it!

a variant (with SetValue() instead of ":=" )

But maby less robust.

and if you enter 2=2..?

and if you enter y=x, the line is created in graphics (not sure that Kelava want this...)

Edit : very strange sometimes works at start, sometimes not :(

Well, I don't want any of the things jumera said but I did it with some extra code - it's not nice and it looks very complicated but it works as I want :-) You cannot enter anything except equation.

The equation (or anything except equation) you enter is deleted :

• if you valid your equation

• if you clic on the button provjeri

If you want this... it is nice...

There are some improvements for this coming in v563. To take advantage you'll need to make sure your random numbers are in their own objects so change

m = If(b ≟ 2, RandomElement({-4, -3, -2, -1, 1, 2, 3, 4}), If(b ≤ 4, RandomElement({-2, -1, 1, 2}), RandomElement({-1, 1})))
n = If(a ≟ 2, RandomBetween(1, 4), If(a ≤ 4, RandomBetween(1, 2), 1))

m1=RandomElement({-4, -3, -2, -1, 1, 2, 3, 4})
m2=RandomElement({-2, -1, 1, 2})
m3=RandomElement({-1, 1})
m =If(b ≟ 2, m1, If(b ≤ 4, m2, m3))

n1 = RandomBetween(1, 4)
n2 = RandomBetween(1, 2)
n=If(a ≟ 2, n1, If(a ≤ 4, n2, 1))
