Program working in 2019 version but giving 0 values in 2015 version

[Beginnermna]

Hello

I have a code that incorporates 'iirnotch' filter and 'trapz' function through mathscript RT module. I wrote in labview 2019 version and it worked fine. But when I saved it for labview 2015 version and ran it from another computer, it is giving all 0 values for all outputs. What should I do?

Attach the code so we can debug it!?

Don't use MathscriptRT module for some filters?

Don't use MathscriptRT for some integration of data?
