Re: Number Table and ForAll

Clicking the Url field in the collection does nothing. It doesn't appear to go any deeper. Setting an image control to First(colEarthquakeMapsWithIds.Url).Url will show a map. I think "Url" here is a binary data type that PowerApps shows as a nested table but isn't actually one.

Re: Number Table and ForAll


So in your more recent posts, you had a collection with id's of all 10.  First, did you resolve that?

With the formula you are using, you will need to have those be valid.  That is, if you are using what was the wtf collection.  If you are using the colEarthquakeMapWithIDs collection, then I am guessing that the mapImage is a table, and within it there is a Url column?  I didn't ask specifically about this.  

However, *if* the collection is as it seems, then Lookup(colEarthquakeMapWithIds, id=varZoom).mapImage.Url should be working for you.

Here is what I would do to troubleshoot...

Put an image on the screen and set the Image property to

    First(colEarthquakeMapWithIds).mapImage.Url  - according to what I "see", that should work.

If no joy, change to:


Basically, trying to understand what your Url is...a table or an image.

Once you get something to show up, then replace the inner part of the above formula with your lookup (let's say the last change above works):

   First(Lookup(colEarthquakeMapWithIds, id=1).mapImage).Url

Then change the 1 to other numbers and see that you get results.

If that produces anything you are expecting, then change the 1 to Slider.Value


Give that a shot and see.  It's hard to say for certain without knowing what that Url really is...
