I've been tearing my hair out over this since this morning and I just can't work it out. The item in the select box should return a list of teams- which it does, but when I check the value returned it is : a:1:{i:0;s:3:"207";}

 

I would be eternally grateful for some help with this or even for just a hint.

 

I know this is Wordpress but I thought it was more of a php question so I posted it here. Feel free to move it if need be.

Actually, it was because I used the same variable $meta further down in the code and defined it as an array

 

Thank you to whoever tried to help.
