Trouble creating a mod

Hi, I am hoping someone can help.

I have created a simple mod, it bumps up the staff limit to 1250 for anyone wishing to try that insane number out. The problem is, the mod shows up in the main menu but nothing is changed in game.





Here's are the contents of each file:

ModAddon.xml
<Database>
<GameDBAddon ID="MORE_STAFF"> <Author>Paximperia</Author> </GameDBAddon>
</Database>

ModStringTableEn.xml
<Database>
<GameDBStringTable ID="MORE_STAFF">

<LanguageCode>en</LanguageCode>
<LanguageNameLocalized>English</LanguageNameLocalized>

<Contributors>
<Name>Paximperia</Name>
</Contributors>

<LocalizedStrings>
<GameDBLocalizedString> <LocID>MORE_STAFF</LocID> <Text>More Staff</Text> </GameDBLocalizedString>
</LocalizedStrings>
</GameDBStringTable>
</Database>

ModTweakables.xml
<Database>
<!-- Override the default tweakable value -->
<GameDBTweakableString ID="TWEAKABLE_EMPLOYEE_LIMIT"> <Value>1250</Value> </GameDBTweakableString>
</Database>

Am I missing something?

I used the wrong variable, string rather than integer.
