In a powerautomate I need to update a sharepointlist item

[dmclaughlin]

In the update item I have this expression on one of the colums in the flow

sub(int('Floater Used'),int('Number of Days')) and

sub('Floater Used','Number of Days')

I've tried both ways. The thing is column 'floater used' and 'number of days' are both numbers in the sharepoint list already so I tried the Int function just as an attempt

I'm getting this error
InvalidTemplate. Unable to process template language expressions in action 'Update_item_2' inputs at line '1' and column '3290': 'The template language function 'sub' expects its first parameter to be an integer or a decimal number. The provided value is of type 'String'. Please see https://aka.ms/logicexpressions#sub for usage details.'.

Hi @dmclaughlin ,

Do you want to use the column value in the SharePoint list as the parameter of the sub function to update the SharePoint item?

You could assign the values of columns in SharePoint to variables, and use the variables in the sub function to obtain the calculation results. I have test for your reference, please try the following workaround:
