The fuel line (line 4) is the only line which contains the fuel data in the six line chunk. the six values you see are repeated every second, so in the example the next fuel figure is line 10 then line 16.

the other values are not connected.

i first executed the first insert which sent the auto incremented row to the table phpvms_pireps.

Then a second execute like so

put "select last_insert_id ( ) from phpvms_pireps" into tpirepid

Re: Using Random number as a percentage

I found the cause and it was as i suspected. Load is a reserved word in MYSQL. In order to use it in a table or column name it needs to be surrounded by back ticks `load`.

Re: Using Random number as a percentage

Thanks Bernd

I had seen that in the dictionary but couldn't figure out where or how to implement it.
I noticed an example using random elsewhere which is where i got the current script from.

could you show an example on how to use that function.

Thanks
