I am building my first app and coming up against some issues. The app I am building will be used to record petty cash transactions - The image below shows the columns set up. The calculations relate to where users can enter details of money spent, or added to the balance.
My question is where is best to do the calculations? i.e. subtracting the spent amount or adding the top-up to/from the balance.
I made a Calculated Column to do this on the SharePoint List (BalanceSum) but this has given me issues with displaying the amount in the app as the current balance in that it displays too many decimal points and "[$-en-US], £0.00" only works with number columns and not calculated ones for some reason. So would it be better to do the calculations within the app before passing the data back to the list?
Also any advice on doing the sums would be helpful, especially on how to get the BalanceBF in line 2 to equal the BalanceSum of line 1 (in the List or in the app)
Solved! Go to Solution.
Calculated fields in SP are converted to Text type in PowerApps, tha's why the formatting didn't work for you. wrap your column in the Value() function to convert it to number and then use the formatting.
Text(Value(YourSPColumn), "[$-en-US], £0.00")
I've attached a screen shot of the result when I try to display the BalanceSum in the app. I'm sure I'm missing something pretty basic.
The box in the screenshot is just placed on a screen, but I have another (on a different screen) which is a datacard on a form. Both give the same result.
When you use something like BH_PettyCash.BalanceSum, you refer to the entire column, not a single value. you need to specify the record in the list to be able to get the value out of the column.
for now, and just to see if your formatting formula works, create a temp Gallery that has a simple layout with only one Title label. Then bind it to BH_PettyCash list. then change the formula of the label to ThisItem.BalanceSum and apply the formatting formula to it. and see if the gallery shows the correct format.
@Edwin-Abdalian Thank you for your help, although not 100% successful it did guide me toward the answer 🙂
I made a new app as you instructed with a gallery with just one label with the list as the data source.
ThisItem.BalanceSum = 200.000000000000
Text(Value(ThisItem.BalanceSum)) = 200
However, after some experimenting I found that this worked:
Text(Value(ThisItem.BalanceSum),"[$-en-US]#.00") = 200.00
@Edwin-Abdalian Not sure if you can help with an additional query on this subject.
Text(Value(ThisItem.BalanceSum),"[$-en-US]£#.00") returns the result of £200.00 which is the correct FORMAT, but not the right result. I want to get the LAST record in the list. However, after much experimentation I have not found how I can add LAST to the existing formula. Any ideas?
