Image check for two images over a certain timespan

Hi,


I'm having issues getting my script working.
To make it pretty easy I'm going to check for a certain image which contains the first digit of the character health.
The images I used for that are namen 5khealth and 6khealth.

I want the script to scan for either of those for a timespan of about a minute with an interval of 1second (more or less).
After the above criteria has been met it should go on with the script.

I tried it this way but it wont work:


if (exists("6khealth.png", 1) or exists("5khealth.png", 1)) then

loop = 1

else

wait(1)

   end
Help is appreciated.
