I know this is just a simple syntax but just can't get the right order !

Trying to disable a button if a text box is empty AND a collection is empty. No errors but it only works one or the other. So if I put something in the text box and not in collection or vv it switches to edit mode. Here's what I've tried

If(IsBlank(txt_landing_pushnotificationtext) && IsEmpty(coTest),DisplayMode.Disabled,Edit)

If(IsBlank(txt_landing_pushnotificationtext) AND IsEmpty(coTest),DisplayMode.Disabled,Edit)

If(IsBlank(txt_landing_pushnotificationtext) && IsBlank(coTest),DisplayMode.Disabled,Edit)
If(IsBlank(txt_landing_pushnotificationtext) AND IsBlank(coTest),DisplayMode.Disabled,Edit)

I know someone will look at this and see exactly what I'm doing wrong but it ain't me ! 🙂

TIA

The following will have display mode disabled if txt_landing is blank and cotest is either blank or empty.

With({blnk:IsBlank(txt_landing_pushnotificationtext), emp:IsEmpty(coTest)||IsBlank(coTest) }, If(blnk&&emp, DisplayMode.Disabled, DisplayMode.Edit) ) )

They are temporary variables. Think of them as aliases for your formulas.

If you are evaluating a collection, IsEmpty() is sufficient, perhaps this is the reason it didn't work. I switched the logic in the formula below?

With({blnk:!IsBlank(txt_landing_pushnotificationtext), emp:!IsEmpty(coTest) }, If(blnk&&emp, DisplayMode.Edit, //Edit enabled only if there is data in DisplayMode.Disabled) // the textinput and the collection ) )
