What is wrong with
int CityIDs() = { 7260226 }; //Only USE ONE for weather marquee
The problem is not with that line but a previous one that is not properly terminated with a semicolon
If you need more help then please post your full sketch, using code tags when you do
In my experience the easiest way to tidy up the code and add the code tags is as follows
Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.
It is also helpful to post full error messages in code tags as it makes it easier to scroll through them and copy them for examination
- as per @UkHeliBob (no ';' on preceding line is the reason for the actual error in the topic)
- if its meant to be an array then it needs
[]not(). - if its meant to be a function it should contain statements not just a value.
- if its meant to be a single variable then it doesn't need brackets and the value is much too large for it to hold. Maximum value range a 16-bit
intcan hold is from 32767 to -32767. To hold a value of the size shown would require anunsigned longtype.
The rest of the code is needed for context.
After seeing 4 errors in just one line, I'm worried about the rest of the code...

The line above the one that you originally showed us was just a comment, so the error was actually two lines above.
It was a missing semicolon.
String APIKEY = "e03f130a375247eccd9cb4390af7f4c5" ; // ; was missing on this line
// Default City Location (use [Find - OpenWeatherMap](http://openweathermap.org/find) to find city ID)
int CityIDs() = [7260226]; //Only USE ONE for weather marquee
Thank you for posting the code, but you didn't follow the advice from @UKHeliBob: 
:
You can still retrospectively add them by editing your post, highlighting all of the code and clicking the <CODE/> icon at the top of the editor window. The reason we ask this is because the forum software then formats the text using a colour scheme to make it much easier for everyone to read. If you could do this it would be appreciated. 
Was it that hard to understand what @UKHeliBob wrote and just check the line before the error (to immediately realize that that's where the semicolon ";" is missing) instead of posting the entire code (without formatting it properly as asked, by the way)?
Anyone who knows a little about C can understand that that error simply indicates a missing semicolon.
Did you miss the bit about using code tags ?
Sorry I'm new ! I do not know what really mean . i sent the code what do i need to do ?can you give example ? Where do you put them ?
Did you read my earlier post ?

The highlighted area is what is wrong I can’t see what is wrong with it !!
Will I didn’t wake up knowing this stuff like you !! I just started doing this a week ago !! Thanks
@mstrunk4 Did you make the correction suggested by @JohnLincoln in Post #6?
Did you create a mix of David Payne's code, or where did you copy it from?
I ask because I can't find this code in his repository, and it's unlikely he would have made such a mistake.
No code tags again
Was that deliberate ?
Don’t understand what you mean? Can you give me an example ?
Follow the instructions previously posted several times in this topic
That fells into my "Anyone who knows a little about C".
If you lack this basic knowledge, don't be offended, but I think you'd be better off learning the C language and getting some practice before you go out and try to do things you don't even know the first thing about...
You have been registered on the forum for six years.
What the example do you need? You were instructed what to do multiple times.
Didn't you know how to add a ";" at the end of line?
