Using a variable to refer to a field

I have a series of fields named pHlp1,pHlp2 ...
Trying to find the first empty field (if any) and store that in another field... iFA (First Available)
Code: Select all
repeat with N=1 to 15
put "pHlp" & N into emptyFLD
if fld emptyFLD of cd"Page 2" of stack"MJADMIN" is empty then
put N into field "iFA"
exit repeat
end if
end repeat
I've tried quite a few different things on the third line to no avail.
I know this is basic but can't seem to find the answer.

Hi Tom,
syntax seems correct!
What does not work?
Best

I dunno, Tom, while I wouldn't have gone this way, it works here with this setup -
...so at least one question comes to mind.
When you named the fields, for instance, is there a space between "pHlp" and the number? That would sure throw off the code.

Sorry Bogs
Where I have the problem is in the code that uses the result. I didn't have any coffee when I wrote the post.What I posted works swimmingly!
I'll work that for a few minutes and get back.

Hi Klaus and Bogs!
Here is where I have the problem.
Code: Select all
repeat with N=1 to 15
put "pHlp" & N into emptyFLD
if fld emptyFLD of cd"Page 2" of stack"MJADMIN" is empty then
put "pHlp" & N into field "ifa"
exit repeat
end if
end repeat
if the hilite of btn "ic1" then
put fld"ifa" into tfirst
put the label of btn"ic1" into fld"&tfirst" of cd"page 2" of stack "MJADMIN"
end if
Thanks

The only problem I see is:
Code: Select all
...
## put the label of btn "ic1" into fld "& tfirst" of cd"page 2" of stack "MJADMIN"
## results in -> field "&tFirst"
## Since this is a STRING!
## You should have seen the error -> no such object
put the label of btn "ic1" into fld tfirst of cd "page 2" of stack "MJADMIN"
...

Please use some more SPACES to make you code better readable.
And you can directly use concatenated object names if you use parens:
Code: Select all
...
repeat with N = 1 to 15
if fld ("pHlp" & N) of cd "Page 2" of stack "MJADMIN" is empty then
...

Trying to find the first empty field (if any) and store that in another field.
That problem, seems a bit funny depending how you read it:...
...and store empty field content (?)...into something else ?
(just kidding trags3 )

Hi Liveme
Here is an explanation of what I'm doing in this part of the App.
I have a set of fields that hold a list of selections by the user. I this case the number is 15.
The user may delete a field for any of a number of reasons.
I want to keep the list (is the word congruous?) with no empty lines in the middle of the list for cosmetic reasons. Also I need to find an empty field if another item is added to the list.
That is the whole purpose of finding the first empty field in a list and putting the number or other reference to that field in another field. ie fld"iFA" (First Available.)
I appreciate all the help I've been given off and on for the past 6 years
Tom
