PDF with the form showing the problem.

Hi,

PDF Form caluclation does not work at all. If you add numbers to the columns with the "EUR" header, the cells should be added up in the Row with the label "Summe", however nothing happens, the calculated sum amount remains 0.00. 

STEPS TO REPRODUCE
1.  Open Attached Document 
2. Populate some columns with amounts (digits only)
3. Look at the row with the label "Summe" - the summed up values should show up there. 

OBSERVED RESULT
Amounts are not summed up in the "Summe" row

EXPECTED RESULT
Amounts should be summed up in the "Summe" row


SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
KDE Frameworks Version: 6.14
Qt Version: 6.9.1

ADDITIONAL INFORMATION
The PDF Form works in the pdf.js viewer included in Firefox. The Amounts are properly summed up there.
