Hey, I'm trying to calculate distance between two postcodes, one is fixed in the gallery (end) and the other is manually typed in the text input (start) i have a label in the gallery which calculates distance with the below formula:

BingMaps.GetRouteV3("Driving",start.Text,end.Text,{distanceUnit:"Mile"}).travelDistance

Trouble is, when the text box (start) is empty i get an error. Is there a way i can manage this error? if so, how? i'm new to power app building and i'm struggling to get over this hurdle.

Hello @jsmith87

EDITED: I initially put "Id" instead of "If"
On your label, maybe do this:

If(IsBlank(start.Text),"", BingMaps.GetRouteV3("Driving",start.Text,end.Text,{distanceUnit:"Mile"}).travelDistance )

@jsmith87

Make the visible property of the label: IsBlank(start.Text) || BingMaps.GetRouteV3("Driving",start.Text,end.Text,{distanceUnit:"Mile"}).travelDistance

By the way, another way of doing it would be:
IfError( BingMaps.GetRouteV3("Driving",start.Text,end.Text,{distanceUnit:"Mile"}).travelDistance ,"" )

Hi, thanks for your help. I've tried this and the label now shows True, this is regardless on whether the text input (start) has a postcode or not
