Help with inserting multiple float values on a single tag

[newbie43]

Hello
Has anyone here ever set multiple float values on an attribute that has a VM of 6-n and a VR of FL. Ive tried calling it like this

float SomeFloatOne = 1.0;
float SomeFloatTwo = 2.0;

// to insert the first float
my_seq->putAndInsertFloat32(DCM_MyTag, SomeFloatOne, 0, OFTTrue);
my_seq->putAndInsertFloat32(DCM_MyTag, SomeFloatTwo, 1, OFTTrue);

or am i suppose to put all the floats in the call seperated by a comma? like so putAndInsertFloat32(DCM_MyTag, 1.0,20,3.0, 0, OFTTrue);
that didnt work either. Status coming back when set is EVR 7
Ive also tried swapping the OFFalse and it still just keeps setting a single float value in the output file. The value is the last float.
I need it to look like this (1.0,2.0) any little example code or help would be appreciated
thanks

Did you try below functions?

OFCondition putFloat32 (const Float32 floatVal, const unsigned long pos=0)
set particular element value to given float

OFCondition putFloat32Array (const Float32 *floatVals, const unsigned long numFloats)
set element value to given float array data

Three questions to the original poster:

1. Which version of the DCMTK are you using?
2. What is the type of "my_seq"?
3. What is the value of "DCM_MyTag"?
