how to add the values of a number of fields.

[CAsba]

Hi,
I have 6 fields where the user enters opening bank balances for 6 banks. I need to add the values of the 6 fields to determine if the total is more than zero, which indicates that at least one field is now not "Balance pending". This info is necessary for the next coding step. I have tried

Code: Select all

put field"pg1" + field"pg2" + field"pg3" + field"pg4" + field"pg5" + field "pg6" into field "sum of balances"

and

Code: Select all

put sum(field"pg1", field"pg2") into field "sum of balances"

without success.
How to do it ? Please ?

Did a quick test and this works fine for me:

Code: Select all

...
put field "pg1" + field "pg2" + field "pg3" + field "pg4" + field "pg5" + field "pg6" into field "sum of balances"
...

I get error message 'operators +: error in left operand.
Could it be because some of the fields conents are not numeric ?

yes
I was just going to say you should make sure there is no comma in the values you're trying to add (keeping in mind that the default decimal point is a period, not a comma as it is in many countries. Needless to say this only works on pure numerical values - but you probably beat me to it

The dictionary is always helpful - look up 'sum':

sum(<numbersList>)

where: numbersList is

• a sequence of parameters, each a number or evaluating to a number or
• a single parameter which is or evaluates to
• a comma-separated list of numbers or
• an array containing only numbers

Why didn't you write this important info in your posting?
What stam said, you need to check if the field contains a number.

Thanks guys, that's set me straight.

Do you know how to check that?

Code: Select all

If fld "pg1" is a number and fld "pg1" is a number and...

Just for the exercise, you should do that better, so that any field that is NOT a number is flagged for you.This is best done in a loop, something like:

Code: Select all

on mouseUp
   repeat with y = 1 to the number of flds
      if fld ("pg" & y) is a number then add fld ("pg" & y) to field "sum of balances"
      else
         answer "Field" &&  ("pg" & y) && "needs looking at"
         exit repeat
      end if
   end repeat
end mouseUp

Of course there are likely other fields on the card that are NOT of the "pg" type. Can you see how to only examine those that are?

Also it is good technique to have a space between the control type and the literal name:

field"pg1" should be: field "pg1"
