new Items = 0;
for(new i = 0; i < 10; i++)
{
     if(!isnull(Statistics[playerid][Item][i]))
     {
           Items++;
           continue;
     }
     else
     {
            strmid(Statistics[playerid][Item][i], inputtext, 0, strlen(inputtext));
	    Items = 0;
	    break;
     }
}

That's how your method should be done.
