I have a filtered portal (by date) with a summary field in it "Total Packet cash"
The summary field has an object name
onWindow open or date selection change my script goes to the object and copies the result to a variable (for use in an addition calculation)
If the summary field has a value, there is no problem.
If the summary field is empty, then the variable is no longer filled with "", but with an unfiltered summary of all records (a big number).
This bug happens ONLY in the latest version of Filemaker Go 15
It does not happen in Filemaker Go 14, nor does this happen in Filemaker Pro Adv 14
