| Thanks Reinder! I've added a small fix in the version I use as it seems there's a little bug if you do an Add (e.g. name A, value 1) then another Add with same name A and value 2, your proposed code doesn't seem to do a replace (so you end up with 2 values A (A=1¶A=2 instead of A=2). So I now have replaced: If ( xPosition ; Replace ( list ; xStart ; xLength ; value ) ; list & name & "=" & value & "¶" ) ; // add by: If ( xPosition ; Replace ( list ; xStart ; xLength ; value ) ; list & if ( list = "" ; "¶") & name & "=" & value & "¶" ) ; // add PS: Also it seems current version of FileMaker doesn't like to use "list" as a parameter anymore (reserved word?) so I have renamed that too. Hope this helps. |
