Hi all,

I am a bit confused...

I set the Default of a text input (which is within a data card, hence the Parent.Default) to:

If(
cvar_call_now = true,
Text(Now(), "hh:mm");
UpdateContext({cvar_call_now: false}),
Text(Parent.Default, "hh:mm")
)

If I have understood everything right so far this should not result in ant problems. It does however generate an error "expected operator" without specifying where it actually wants an operator. I assume the semi-colon after the Text(Now()) is the offender because I added the Update Context just before the error occurred.

What's my mistake here? I was under the impression that one could place any number of lines within the result of a condition as long as ";" is used to separate those lines (many posts here on the forum told me so).

It is definitely not the fact that I am changing the variable that lead into this branch of the condition (thought that might be the case and just made it update any random variable).

TIA for all the good ideas

Hansjoerg

Hi @ha_wai ,

You cannot use an action in the Default of a control - firstly the Default

Text( If( cvar_call_now, Now(), Parent.Default ), "hh:mm") )

however your logic is a bit baffling on the Variable part - you are saying if c_var_call_now is true set it to false - what conditions need to be present for this to happen?

Hi @WarrenBelz ,

thanks for clarifying that. Not nice, but at least helpful.

To answer your background question:
cvar_call_now is set to true by a button with the intention to register the time the button is pressed. If I don't turn it off after it's been used it will constantly update the value of the text input. Not what I had in mind.

What I am clumsily trying to achieve is a data card with a date/time field that can be edited by either pressing the "now" button or by manually entering a time. I'm currently struggling a bit with the logic behind it (being not a SW developer at all).
The general setup is:
The App is going to record various timepoints in our hospitals patient transfer service (team leaving, arriving at scene etc..)
EditForm that gets it's data from a Gallery in another screen. Each DataCard to represent one date/time field in a sharepoint list. And each data card to have a big "now" button that the user is supposed to press when a certain event happens. But it should also have an edit function to manually enter a time in case the user didn't press the "now" button at the correct time (the nature of the patient transfer doesn't always allow for timely documentation).
So far the only solution I could come up with was trying to manipulate the content of the textinput field and then writing it back to the list with Patch().

I am open to any other suggestion, but I am not expecting anybody here to solve my conceptual problems here 🙂

Cheers
Hansjoerg

Hi @ha_wai ,

You can initiate a trigger action on the OnChange of a control, so whatever input changes the "status" could be used to reset the Variable.

Hi @WarrenBelz ,

apologies for the delay, this project is just a side show to my normal job, hence the irregular attention to it (which doesn't really help either) and thanks heaps for the offer to help.

I think I am currently pursuing a promising approach.

Should this fail I will have to find a way to actually put my problem into a set of questions that can be answered via the Forum. Hope this won't be necessary.
