Group band condition more fields

Oronzo

I use FR6 with Delphi 10.4.2. One of my reports contains a group band with the condition:

<tbCgMovM."DataReg">+<tbCgMovM."TP">+<tbCgMovM."NProt">+<tbCgMovM."Causale">

DataReg is a date field, the others are text, numeric, text

when I run the report I receive the following message

Any suggestion will be appreciated.

Thanks

Try VarToStr(<tbCgMovM."DataReg">) + VarToStr(<tbCgMovM."TP">) + VarToStr(<tbCgMovM."NProt">) + VarToStr(<tbCgMovM."Causale">)
