Hello everyone!

My first of many questions while I learn the language and commands.

I'm ace at excel which is helping but leaves me stumped at certain times.

Below is the command I have on a 'Login' button, but even when the 'OpName' has text in, the form won't navigate and keeps displaying the notification:

If(!IsBlank('OpName'),Notify("Please enter your name"),Navigate('Home screen',ScreenTransition.Fade) )
 
Thanks very much in advance all!

Hi NR-02100941-0,

I think you wish to notify the user with "Please enter your name" message when the text is blank, right?

Your condition in the code says -

if the OpName is not Blank, Notify, otherwise Navigate

It should be-

if the OpName is Blank, Notify, otherwise Navigate

Update the code to this:
If(IsBlank('OpName'),Notify("Please enter your name"),Navigate('Home screen',ScreenTransition.Fade) )

Hope this helps.

Kind regards,

Nandit

So If i understand correctly, '!' negates the argument?

Class.

On the back of that, I can now 'login' with the form OpName being blank. I'll dig deeper, certainly something simple no doubt.

one option is to disable the login button while OpName is blank
on DisplayMode of Login button you can add
If(IsBlank('OpName'), DisplayMode.Disabled, DisplayMode.Edit)

bump on this because it's still allowing me to 'login' despite the field being blank.

Thanks all again

If the 'OPName' is a text input you would have to specify that it's text is empty... so use code like this

If(IsBlank('OpName'.text),Notify("Please enter your name"),Navigate('Home screen',ScreenTransition.Fade) )

it didn't like the ".text" on the end there.

It is a text input field also.

if I change the isblank to reference the form instead of the text box, it still won't work hmmmmm
