i've made a panel where my text is scrolling via an ultra-elemental function. which copy a string to the next.

Code:
function logger(text)
{
	str_cpy(log_str1,"");		 // clear the string
	str_cpy(log_str1,log_str2);
	
	str_cpy(log_str2,""); 		// clear the string
	str_cpy(log_str2,log_str3);

	str_cpy(log_str3,""); 		// clear the string
	str_cpy(log_str3,log_str4);

	str_cpy(log_str4,""); 		// clear the string
	str_cpy(log_str4,text);
	wait(1);
}


the function will receive a string that will be copied to the line 4.
the problem is when the strings arent strings ! :-\

so my answare is: How can i brutally convert the value to a text that can be displayed ?

i mean, i wish to use some simply

logger("Erica say: hello");

but i can use also

logger(my.x);

i've tried something like
logger(str_cat_num(temp_str, "%.0f",my.x));

but the game give me the error:
invalid arguments in player_ctrl (which is the action that call the funcion)
