Graph :cursor error

[JefS]

Hello

I have a graph with two cursors in it. Those cursors help me to set an interval. After that I can calculate max., min. and mean values of the interval. 

When I open a saved graph I often receive this error: error-1801 occured at start value toot large in Get Waveform Subset.VI. 

I've tried many things but still no results.. I hope someone on the firum can solve the problem.

Tnx!

You might have better luck if you actually post a vi, not a picture embedded (somewhat unhelpfully) in a word file.
