control references

Hi Doug,

It seems to me that you are asking too much in expecting the same code 
to handle a reference no matter whether it is a short reference or a 
long reference, and a name, number or ID. If you have a field called 
"Data" and you pass it's short name to this script, it's parameter is 
going to be "Data" which won't work.

I would start by insisting on a single reference type, say ID. Once your 
basic script is working properly, perhaps you could put in some sort of 
testing to see what sort of reference was being passed and convert the 
reference to a standard form for use in the rest of your script.

When testing your script altered in this way, I had a weird problem with 
your variable names: f1Text & f2Text didn't work properly. They appeared 
twice in the Script Debug variable list. One of each got set correctly 
to the contents of the field, the other pair got left empty. Once I 
changed the variable names, the following script worked fine:

on mouseUp
   put the ID of fld "Start" into startID
   put the ID of fld "End" into endID
   equalizeNlines startID, endID
end mouseUp

-- this just swaps the contents of the fields
on equalizeNlines f1, f2
   -- f1 and f2 are short IDs of fields
   if there is a field ID f1 and there is a field ID f2 then
     put fld ID f1 into var1
     put fld ID f2 into var2

     put var1 into fld ID f2
     put var2 into fld ID f1
   end if
end equalizeNlines

Note that if your script has:
	put "field 1" into field "New field"
then the text "field 1" will go into the field.
If you leave off the quotes and say
	put field 1 into field "New field"
then the contents of field 1 will be used.
