Propeller Memory Card, writing data to SD

Just started working with the Propeller Memory Card. I'm trying to wring a string to the SD card but I can't get a long to appear with the rest of the string.
I'm using the SD-MMC_FATEngine.spin
The string is meant to communicate with MegunoLink. Here is the PUB
SD.writeData(@data, 4) is the line I'm having trouble with, I either get blank spaces or jibberish for this portion of the string output.
Here is a sample of the output I'm currently getting.
thx in advance for help

PUB MegunoString (data, seriesName)
{ Create a string for MegunoLink to read and generate a time plot from
data: type long, sample data from an external sensor
seriesName: type string, the title for the line that MegunoLink will plot to represent the data
}
SD.writeString(@_timePlot)
SD.writeString(@_channel_1)
SD.writeString(@_data)
SD.writeString(seriesName)
SD.writeString(@_t)
SD.writeData(@data, 4)
SD.writeString(@_endPlot)
SD.writeData(@data, 4) is the line I'm having trouble with, I either get blank spaces or jibberish for this portion of the string output.
Here is a sample of the output I'm currently getting.
{TIMEPLOT:Altitude|data|Sensor Altitude|T|] }
and this is what I expected
{TIMEPLOT:Altitude|data|Sensor Altitude|T|]345}
thx in advance for help
