PIC16F876 + QV306m4 Problems

[pcaccia]

Hi All.
I'm Paolo from Italy ...a new member! I read threads on this great forum and I think I learn very much, but I'm a novice ... and the solution of some problems aren't write in manuals and datasheets but only with much esperience.
I'm sorry for my bad english but I hope you can understand my problem:
What the software must do:
I read serially a signal from a wether station
Some values are stored and when I press one button, I send serially commands to control a quadravox QV306m4 sound module to speach all values.
The problem is great and only one! When I push the button the QV306m4 sound well only some world or number...and not all.
I can say:
1 The qv306m4 works ok (tested with my PC directly)
2 The software of the peek read perfectly the input serial port
3 The output code to control the qv306m4 aren't totally correct...as I can ear in the speacker of the qv306m4 but the software seem to be ok..HI
In the attachment you can see my terrible software..plase don't kill me ..it's my first software on pic.

I think the problem is in my software for the compatibility with a PIC ...too much gosubs routines, or too much var word or con...I don't know!
Thanks for reading and help
Paolo
