Hi Simon,

This clearly sounds like a bug to me too. I know, that you can not use such expressions in Property sheet, where you're limited to 255 chars, but why you have problems in the code?

Thanks.

I think, the problem also can be in the variable lenght of the final result. May be if Chris will padr the whole expression to fixed lenght, this problem goes away by itself? Just a SWAG.

>>I think that controlsource cannot be longer than 255 characters. Add a method to the form, put your code there and call it from grids controlsource. Something like

* mymethod
>>Return alltrim(v_custlist.cu_addr1) + iif(empty(v_custlist.cu_addr1), "", " ") +
>>alltrim(v_custlist.cu_addr2) + " " + alltrim(v_custlist.cu_addr3) + " " +
