Complete amateur here... Trying to find the correct formula for a text label to display the time elapsed in minutes in a gallery since a button is pressed in a form.. my limited knowledge i come up with this....

DateDiff(Button1.Pressed,Now(),Minutes)

But naturally i get an error.. Can anyone possibly guide me in the right direction..?

Thank you!

The problem with this will be that the label in the gallery won't automatically update on its own without it re-evaluating what Now() means. For example, you can test this yourself:

Button OnSelect():

Set( varButtonPress, TimeValue(Now()) )

Label Text():

TimeValue(Now()) - varButtonPress

Select the button, add that into a label, and wait a few minutes. Notice how nothing changes? That's because it'll only evaluate Now() once in that label until you tell it to do so again.

You can get the effect you want by using a timer:

Button OnSelect():

UpdateContext({TimerStart:!TimerStart})

Timer Start():

TimerStart

Label Text():

Text(Timer1.Value,"mm:ss")

Depending on how long you anticipate a user staring at it, you might need to increase the Duration() property of the timer.

You can hide the timer by setting its Visible() property to false! To my knowledge this is a clean way of accomplishing what you want. Otherwise you'll have to rely on a bunch of OnSelect() statements to set/reset variables and to re-evaluate what "now" is.

Right you are! You'll have that button's OnSelect() be:

UpdateContext({TimerReset:true})

Also, if you want that button to also start the timer again, use this instead:

UpdateContext({TimerReset: false}); UpdateContext({TimerReset: true}); UpdateContext({TimerStart: false}); UpdateContext({TimerStart: true})
