Hi @sirtommy, unfortunately, I was not able to access your file, but I created a simple example that you might find helpful.
The file has a droplist, a repeater that contains three columns: Types of fruits, Subtypes, and Price, and the text label “Label_sum” that keeps the information about the current total for the column “Price”, which I store in the global variable “Sum”.
I used the “Selection changed” interaction for the droplist along with some conditions so that whenever the selection of the droplist equaled a specific value, the filter on the repeater dataset was set with the action “Add Filter”, and I also set the value of the global variable to zero by using the action “Set Variable Value”.
Then, since a repeater is redrawn whenever you modify it-- in our case, when we filter it-- I added the “Item Loaded” interaction for the repeater to be able to count the total value of the filter items along with conditions that checked what selection of the droplist was in place and actions “Set variable value” and “Set Text”, which set the value of our global variable [[Sum]] to [[Sum+Item.Price]], and text of the “Label_sum” to “Total[[Sum]]”.
I hope my file helps, and please let me know if you have any additional questions.DroplistSelection-R_countTotal.rp (62.4 KB)
