Hi Borislav

>Try to debug why this happens:

I had debuged it before, as it was raising an error and codebook errorhandler allows me to debug the error. I also tried your method and I get the same results.

under the Watch panel:
- poText is a textbox based object having the Value property
- poText.Value and I can see the value "ASD ", that I had in the textbox when the call was made
- EVALUATE(cSource) cannot be Watched as Expression could not be evaluated
- &cSource. when Watched gave the Name: poText.VALUE and Value: "ASD " they way I had typed it in

Thanks, I like your way of ASSERTing, with the CB method I had to go down the Call Stack (though no big deal) to the line raising the error.

Thanks.
