simple question

[Guest10]

i try to resolve the error i get in this line:
n:=1
headline1_date%n% <> %headline1_date_%n%%
Error: Empty variable reference (%%).

Well Headline1_date seems to be empty.

[Guest10]

it is actually like this:
n:=1
headline1_date_%n% := "some value"
headline1_date%n% <> %headline1_date_%n%%
Error: Empty variable reference (%%).

Well Headline1_date seems to be empty.

Well, it's considered empty because of the last %%

Code: Select all

n := 1
headline1_date%n% := "apple"
headline2 := "orange"
if (headline1_date%n% <> headline2)
MsgBox It's different!
else
MsgBox It's equal!

headline1_date%n% := "apple"
headline2 := "apple"
if (headline1_date%n% <> headline2)
MsgBox It's different!
else
MsgBox It's equal!
ExitApp

thanks! my question above was posted hastily and not in full. basically, i was wondering if i could wrap % inside of %% (%headline1_date_%n%%), which could end in something like %something%n%%

Something like this?:

Code: Select all

n:=1
headline1_date_%n% := "some value"
something:= "headline1_date_" ; something must have a value
var := %something%%n% ; 2 dynamic variables, the same as headline1_date_1 
msgbox,%var%

thanks! i think in the end, i did something similar:
headline := "Headline: "
ht := headline1_title_%n% ; Must be ":=" NOT "="
hh = %headline%%ht% ; Must be "=" NOT ":="
Title = %hh% >> ; Must be "=" NOT ":="
...
