Give your code for us.
There you can read what is tag mismatch: https://forums.alliedmods.net/showthread.php?t=94187

A tag mismatch is basically a piece of code that is either missing or wrongly defined. For example:

PHP Code:

new Handle:arr = CreateArray(Map);

decl map[Map];
strcopy(map[MAP_NAME], sizeof(map[MAP_NAME]), "cp_dustbowl");
strcopy(map[GROUP_NAME], sizeof(map[GROUP_NAME]), "Attack / Defend");
PushArrayArray(arr, map); 


is wrong, since Map would be wrongly used multiple times. To fix that, you could to this:

PHP Code:

//Manually define size
#define MAP_CELLS 128

new Handle:arr = CreateArray(MAP_CELLS);

decl map[Map];
strcopy(map[MAP_NAME], sizeof(map[MAP_NAME]), "cp_dustbowl");
strcopy(map[GROUP_NAME], sizeof(map[GROUP_NAME]), "Attack / Defend");
PushArrayArray(arr, map[0]); 


Down below is a better example ;)

Actually, a tag mismatch means you are trying to use something typed as something for something expecting a different type.
Your example results in an "Argument type mismatch error" and not a "tag mismatch WARNING"
Note: Warnings ARE NOT ERRORS, a warning means the code was accepted, but it may result in UNDEFINED behavior.

Example of tag mismatch WARNING:

PHP Code:

Handle x = 5; // Tag mismatch: Expected type "Handle" got "int"

You can still count em as an Error in a way, since your code won't work anyways if you have your tags mismatched... ;)

In any other language, this would be a type mismatch compiler error.

The only reason this isn't here is because almost everything is really the type "cell" (read: 32-bit signed integer) in Pawn with a tag telling it if it has a special purpose (Float, bool, Handle, an enum type, etc...). The only exception is String/char which is an 8-bit type.

Wrong. Tag mismatches often still result in code that works as intended.

In a typed language that would be an error unless you cast it (view_as<T>(expr) in our case). It can work, but you better make sure to fix those.
