Another problem is that in the field script your keydown handler is
mis-constructed. You have "on keyDown var, temp, pKey" This is the same problem
you were having before in your mouseup handler. What you have to understand is
that when trapping system messages like mouseup or keydown (or openfield, or
enterinfield, or mouseleave, or..., etc) you are not free to use any parameter
list you want. Each system message is accompanied by a specific parameter or
parameters (or maybe no parameters at all), and the dictionary tells you what
they are.
The keydown message carries with it only one parameter, the keyName. if you
start a keydown handler with "on keydown a,b,c" then the keyname will be
inserted into the first parameter variable "a" and the variables b and c will
be empty. Because of the fact that you put the contents of your first
parameter, "var," into the field, you get what you expect from this. The other
parameters start out empty and then you load them with values. There is no
point in listing them as parameters in the "on keydown" line, since the keydown
message is accompanied by only one parameter. A cleaner version of your keydown
handler would start out:
on keyDown pKey
set the cFlagPhotoGet of field "Type_Name_to_Find" \
of stack "QuickieFinder" to true
put the cNewmanResults of stack "Kids" into temp
put pKey after me
filter temp with "*" & me & "*"
put temp into fld "Filtered_Results"
<snip>
Also, further down you have a "pass keydown" line and then a "send" command.
You should be aware that if you "pass" the message you have trapped, your
handler is immediately exited, and nothing later will be executed.
And -- never never never trap the idle message. It ties up too much processing
time, since idle is sent multiple times per second. There is **always** a
better way to do whatever you're trying to do.
