referencing of the value of a filed on canvas section for web page

[avianmanagement]

Web app, finally decided this is the way to go even with the learning curve for me involved.
Canvas section

I have an edit box that I want to make invisible depending on the value in of a txt box on the canvas section

If I set the visible property of the edit box to 1 = 2 and run it then it is invisible

If I set it to :

Lianja.get("page1.dpref.txtcsex").value = "M"

It does nothing even when the value in txtcsex = M

Can someone please tell me what I'm doing wrong here in the referencing of the value.

In javascript as with many other languages = is an assignment operator whereas == is a comparison operator.

Hi Barry

If I set it to
Lianja.get("page1.dpref.txtcsex").value == "M"

It still does not work, it's invisible all the time no matter what the value of txtcsex is M F or U

I have taken the entry for page1.dpref.txtcsex directly from the txtcsex Full name entry on the form, so the wording for that should be correct

Sorry where are you placing that code.

Switch to runtime view. UI elements in development view will always be visible. Otherwise you wouldn’t be able to design anything.

Hi Barry,

Yes this isn runtime and it is alway invisible with the entry

Lianja.get("page1.dpref.txtcsex").value == "M"

in the visible when entry for the edit box

If I put 1 = 2 it's invisible
If I put 1 = 1 it's visible

But with
Lianja.get("page1.dpref.txtcsex").value == "M"

it's always invisible even when the value of page1.dpref.txtcsex = "M"

I put a command button on the form and added click code
Lianja.showmessage(Lianja.get("page1.dpref.txtcsex ").value)

That works and display the entry, so the value is correct
