conversion from double to integer

[Tamas]

Hi,

I have may be a stupid questio. 

I have a double array, it is an input of the Mathscript, the first two column's  elements like : 1.0000, 2.000, ...etc. I would like to conversion it from double to integer, because I'll use it to index an other array. When I run the VI, I get a run time error. It seems the explicit conversion is not working. In Matlab I can conversion data types on the same way.

Error code -90026 matrix index must be real, positive integer

My code can you see on the picture below.

Please help!
