[WX 22] HErrorInfo (no replies)

I'm having some trouble using HErrorInfo, can't get it to show me what the error was, my code is as follows:

IF ErrorOcurred() THEN
IF HerrorIntegrity() THEN
sError = HerrorInfo()
END
END

Info(sError)

It always returns empty, but if I debug that part of code, and check what HErrorInfo shows in the debugger it actually tells me what the problem was.
