This attached code compiles fine with SX-KEY 3.1 and the older
version of SX\B but I get multiple errors with the new SX-KEY (3.2) and SX\B 1.51.

There are three IF statements and each one fails for different reasons.

Does anybody have any idea what is wrong?

Thanks in advance

Here is the code:
