Relatively new to powerapps and flow and am struggling with a specific use case that I am hoping someone here can assist with.
I have a sharepoint list that is used as a master inventory list for rental equipment. it is set up with an availability column that displays Available, reserved, in use, etc
I am building a power app to be able to reserve/request equipment and I want the user to be able to tell if the equipment is available before requesting it. to accomplish this I am hoping to have a button within the form datacard for the "itemtype" (column that separates the equipment into smaller categories) so that which ever they have selected for example 'skis' or 'ski poles' for them to be able to click the button and that button check the list and return the number of 'Available" items from the list. snip of my list for reference.

any and all assistance is greatly appreciated!!!!
